THE MAN ...... THE MYTH............. THE LEGEND......................
Sure is 👍
@@GSHElectrical a God in the electrical industry
JW knowledge shared freely. Who else smiled when he said hello I’m JW?
We loved it also 😁👍
Ahhh... That iconic opening 👍
You aren't kidding mate!! I smiled ear to ear!
Damn, I think I had it muted without realising. When I invited I didn't think I missed much so kept going... I just played back the start just to hear it. (Sad, I know)
I think that's the first time I've ever seen john ward smile lol, top man and love his dry humor and wealth of knowledge about electricity, Your channel is also very good, I've learned a lot.
Thanks for the lovely comment Gaz 👍
I am here for John Ward.
I could listen to John all day talk about electrics. Bloke is really easy going and nice chap.
He is a lovely chap thanks for commenting Gaz
JW is like a mind reader, I watch his videos and then a question I would like to ask him pops in my head, and then a few seconds later he covers it on the video 👍🏼
The King off electrical rock & roll !!! The man they call the JW -Legend
One the most iconic voices out there. Right along with Big Clive, Andy (Photonicinduction) and Dave Jones (EEVblog). What an awesome day to have JW in the shop passing on some knowledge! What a treat!! And for the non-believers. JW ACTUALLY SMILES!!!! :-O
Wow thanks for the wonderful comment 👍 Gaz
I love the part where everyone claps and he does his best not to smile😁
John ain't knows how to smile, in fact the rumour says even Chuck Norris couldn't make him smile...
I love JW and his presenting style.
JW what an absolute legend, what this guy doesnt know aint worth knowing
True 👍😁
This is what KZhead is all about 👍 Thanks to all involved for the video
Absolute first class. Thanks Gaz for working hard to get legends like JW in.
John Ward the Legend!!!
John Ward is a god !
As always Gaz, brilliant having the the great JW in, thank you JW for taking the time to visit GSH Electrical
Dean it was amazing and a pleasure to have him visit Team Electrical and our learners 👍. Thanks for commenting and watching Gaz 😁
JW look very tall! In 14.02 he smile much more than in his all videos. Great man!
He is... lovely guy as well😁👍
JW brings 'dead pan' to a whole new level - brilliant. Had most of those things in my Victorian house in London before I replaced them, lead, rubber and pvc in the same installation, with lights on a wooden fuse board exactly like John's and 'power' on individual MEM switch fuses running from a Henley, was a bit dodgy even in the 60s I should think!
Stuff like this makes learning and understanding easier.. Clear and simple.. 👍👍👍
Thanks 👍
Another great video by JW 👍
It will leave a great legacy to the future in the coming years. Very chuffed you guys.
0.29 Gary’s looking at JW like omg 😱 it’s actually him 😂😂😂😂
👍🏻
I watch all your videos and I'm not a electrician, find them very interesting.
Thanks Victor 👍
That was a good watch 👍
Thanks 👍
You guys provide such a valuable resource to fellow sparks. Great to see the youtube greats sharing their wealth of knowledge and practical tricks of the trade. Thoroughly enjoyable videos, they're well presented and i appreciate you all making this knowledge so accessible. JW's videos in particular are immensely helpful and insightful. You guys are changing the trade for the better. Where a lot of us may have just plodded along in ignorance, you are nurturing proper practice, interest and injecting a bit of passion back into the electrical game.
Thanks for such a detailed comment 👍. Team Electrical will continue to try and produce content in the future. Thanks again Gaz 🙌
Brilliant the like of GSH electrical and JW can only be a positive thing for the industry. Your students are very luck to have had John share his knowledge. Nice to see a video that could be used as a guide to show home owners when they have old wiring and consumer units. Thanks for sharing
Thanks so much for the kind words 👍 Gaz
I’m not a spark, know completely sod all about electricity but this channel & especially JW have me hooked !! Wish I’d found it sooner !!
Wow amazing comment 👍 we have lots more content to come thanks Gaz
Wow GSH and JW together 👍
Massive respect for John, especially because he looks like he's going to vomit at any minute.
i remember the crabtree c50 dis boards in industry very well . ? i wondered in later years did it mean c tripping curve , the place i worked was very hot and the crabtree seemed to be a very stable breaker.thanks for video .
Excellent
Thanks 👍🏻
That old rubber cabling and the VIR cabling made it all the way down to New Zealand as well. Plenty of that horrible old stuff left here too. Ironically the best condition VIR I ever removed was in an apartment building, it still had cardboard tags attached that said "Emergency War Grade".... Still lots of wooden framed switchboards with rewirable fuses in them too. How we don't have more fires I don't know...
Hi. Thanks for commenting and the news you have them in New Zealand. If installations using these wiring methods don’t start fires why do we need AFDD’S ??? Thanks so much for watching all the best Gaz 👍
@@GSHElectrical Not come across AFDD's in any older places as yet. Was capping and casing a thing there? If not, be thankful.. Capping and casing was essentially wooden conduit, just not round. Imagine a flat piece of timber, say 30mm x 15mm with grooves routed out of it for the VIR cabling and then a thin wooden cap over the length of it. It is good to surround your perished cable with kindling material the full length of your house for a nice even burn...
@@johnsimpson8263 I've seen capping and casing in a Victorian house in Belfast, along with VIR and other ancient wiring methods. When I was travelling Ireland and NI in 2008, youth hostels provided me a glimpse of some of the most interesting and in some instances downright dodgy wiring I've ever seen, including modern-ish PVC 3+E with the outer sheath just crumbling away for no apparent reason - no signs of heat, no particular UV exposure (inside, in a somewhat gloomy hallway), nothing. I've been toying with the idea of adopting capping and casing to modern double-insulated cables suitable for installation against combustible materials though, it certainly looks neat!
Superb as always.
About time it’s been posted ,been waiting agesssssss JW!
One more to come 👍👍
This is excellent. Jw is almost encyclopedic. Fantastic watch.
So good to see both legends together
Thought I should let you know this video has been some help 👍 😉
😁
G'wan JW!
great content as usual
FYI you got my subs thanks to Ward.
He is a legend 👍🏻
I'd just like to mention that I shouted out Crabtree right at the beginning when he picked it up 🤯
SparkyNinja, not to worry. By the way, thanks to you I’ve passed my 18th. And further thanks to you I was disappointed I never smashed it - got 83% instead. This was because you instilled in me, that to understand is what is required, and the passing is just a by product.
Great video. 😁
Nice video. 👍
Great man the JW
Great video! And you hit 18k subs congrats really deserved it!!!
Thanks for the subs shoutout 👍.... JW was amazing
Wow, fused neutrals, dodgey. I’ve never seen one of those before.
Quite a few countries retained them for a long time, fear of N-E faults on TT supplies. I'm in Austria, where until the early 1980s it was up to the electricity supplier whether fused neutrals were required or not. In theory, the regs have required neutral fuses to be replaced with solid links for over three decades but in reality they never are, unless there is a full rewire. I certainly know someone who received an electric shock replacing a light fitting only having removed the neutral fuse, assuming lights being off equal safe working conditions. On the other hand I also know someone who received a shock stripping wires with his teeth, not knowing that his brother had turned the MCB back on because the radio wasn't working. DIYers are just too creative!
Great video 👍👍 Gaz
i love your video.
I want one of those wylex fuse boxes for my collection
Can't put into words why I like JW so much but it's clear lots of people find him just as fascinating. I guess it's his vast knowledge, dry humour and dead pan delivery. Really like the the instructor here as well. I'm sure he is responsible for churning out very good sparks in this country and for that I thank you
He is a lovely guy 👍 all the best Gaz
Great video
I still have a relatively old consumer unit still operating in my shed - it is a MEM Memera 21 with an RCD. It's probably about 20-30 years old.
Frankly, 20 years is almost new. Of course, the regs have changed a bit, requiring more RCD protection and non-combustible enclosures but still, not really all that old. Plenty of 50+ fuse boards still around!
When I was little we had a consumer unit just like the one at 3:44, the button's didn;t like to reset.
Hi thanks for that 👍. All the best Gaz
I will admit i do do diy electric but i will always make things safe and proper insuring that earthing is made and correct cables sizes are used
It’s not true that no electrician would install a metal lamp without an earth. In my parents’ house there were brass wall lights, with brass lampholders, supplied by twin VIR cables, and these had been installed by electricians. In those days, most table lamps had brass lampholders, and were usually supplied with twin flex. Cpcs on lighting only started with the fourteenth edition regulations.
John was the lead sheathed cable designed for Marine use due to corrosion of copper in saline environments..? Just wondering as it seems plausible .
He looked a bit nervous! I suppose being in front of an audience is a completely different thing :)
Hi was but what a lovely guy 😁👍. Thanks for commenting and watching Gaz
4:00 the MEM fuse board, with the button breaker cartridges. One to watch out for which I found on a meter exchange: It's possible for the button with the rating written on to come away from the mechanism. This exposes two pins. When testing with a voltmeter to neutral, for some Godforsaken reason, the pins of the mechanism are live at supply voltage with the breaker unmade. Meaning, of course, if the consumer was to attempt to make the breaker with their finger pressing the pins, they will have a brown pants moment. Not sure why I thought to check but glad I did before prodding at it. The bodies also have a habit of popping apart into lots of little bits if too much force is needed to remove them from their slots. Not ideal when you're limited scope and cannot replace.
Also a comment on VIR, I have seen on at least one occasion in Shropshire, domestic VIR used as overhead supply cable to about four properties. Western Power had replaced the majority of it ~2012 after the customers reported it self-igniting as seen on JW's channel. Inexplicably they had cut out the burnt bit and left the parts terminating into the properties in place, even more inexplicably without a neutral cutout inside the properties (ie service neutral terminated in Port 2 of the meter). The area seems to be a bit of a horror zone for baffling service work.
The comments about no RCD's or MCB's really is pointless, with most of the boards shown RCD and MCB's were not even thought about let alone manufactured. The very first MCB I saw, came from France and was operated by two push buttons-green on- red off. Trip speed could be adjusted using an Avo Meter. Today everything is available and the Regs have been tightened up no end, which is good. Its easy to smirk about old equipment but that was all that was available.The very first MICC (Mineral Insulated Copper Cable) I saw, also came from France. An excellent cable for high risk fire situations, like petrol depots but fell out of favour due to its high labour costs to install.
2:34 "Main problem with these is.....No RCDs" Johns Equivalent of "Did I fire six shots or was it five" lol
No mention that you can get plugin mcbs for the Wylex boxes that can be reset (after checking what the fault was) instead of faffing around changing the wire.
JW doesnt like them and thinks they are a waste of time, no better than the fuses they replace. I think he is wrong, the MCBs have safer tripping curve characteristics compared to fuses, circuits can be easily isolated for maintenance etc and they are more convenient if something happens that causes fault current to flow and they trip, as you said.
@@cbcdesign001 And of course you don't have to turn off the power to the entire house to reset a tripped MCB, which I'd consider a major advantage over rewirable fuses!
👍💪🏼
I think it's true acronym is v.r.i vulcanized rubber insulated and it has been mis-quoted over the years.
Only £50 a call out, give me Jw mobile as I’ve got a shed load of work for him.
My home has three #Wilex circuit boards still...
better than tv .. :) Consumers unit or is it consumer unit ?
consumer unit Thanks for watching Gaz
Fuse Box
Only just got to watching this one. Like both GSH and JW, but god he looked like a fish out of water to start with. Must be a big difference between talking to a light on a camera and facing a load of spotty faced youths.
But what a legend JW is 🦾
lol on yer sell johnny boy
What JW does not know about Electrical is not worth knowing...
Dont like RCDs anywys thats why i never use them :D
bloody adds
Hi. Sorry if the ads caused you an issue.... all the best Gaz
...If in doubt rip it out...
Another great video, as always... One small moan! With the antique consumer units, they may give a loud bang when inserting the fuse, without finding the fault first.! BUT the ASBESTOS flash guards/tapes are the real killers in the older units. Yes, still finding them, in this day and age. As the fuse wire ruptures, exploding into the flash tape, and then, removing the porcelain fuse holder from the porcelain fuse carrier, breaking off fibres of asbestos in the process. Even with items installed in the 70's, like the MEM Excel, Switch Fuse range. No good being a well trained Sparky earning all that money, if you haven't got the lungs to enjoy it in later life..... If all the students have a responsible employer and been on a Asbestos Awareness course, Sorry for the moan. Moan out of the way, Good to see experience and knowledge being passed on. Makes me feel old. GSH. Keep up the relentless good work and time you invest into your students. Regards, Andrew.
Thanks for your detailed comment and taking the time to watch. All the best Team Electrical 👍
Bit of a fail there!
