Notting Hill School 200a Mains Upgrade 

How are you Elliot ? What you up to these days ?

All good mate! Messaged you on linkedin mate. Chat soon!

Thanks for taking the time to appreciate, takes a while to edit the videos so always good to hear feedback

Thanks john I now wear gloves all the time

That’s cool and a small World

Very good comment, the original supply was tiny (100a) exactly down to what you have said. The school in question…. id have to remortgage my house to get my child into

Indeed although I get a cable cutting anxiety 😥

Thank you for the kind words, it’s a new channel and I really appreciate The support

Always a pleasure to hear from electricians from across the pond, i admire the strong conduit usage for cable containment in the US as it requires allot more craftsmanship, the British only use conduit for retro cafes and heavy industry these days.

@@maydayelectricalsolutionsl7601 Yes and in certain areas like in Chicago area, they require metal conduit for all wiring in residential houses etc. I am so glad thats not required where I am at. I would hate to have to run and bend all that conduit in every house to every light and socket. Also having mostly wood stick framed houses its much easier to run cables than having to deal with doing everything in stone and brick like you guys have to deal with in that setting. 🤦‍♂

Thanks for the support spence

Thank you for supporting the new Chanel luke, digital fuse video coming about next week

Body is still aching 😂 thank you for the good words

Thank you john for the support

Thank you Barry

Defiantly a physically demanding job, 400a must have been a pig, what size tails did you have to install?

@@maydayelectricalsolutionsl7601 can't remember now ,but another job using 300mm singles in pairs ie 3 per phase linking income to building main panel on ladder tray 40 metre runs on my own ,

Thank you for the support

Thank you Cristian for tuning in

Hello Paul blimey I look back at them says, how are you Paul and did you find the channel by chance?

@@maydayelectricalsolutionsl7601 yeah I was just on you tube and see your channel looks like your doing well .

Thanks will, glad we are a little bit different so far

More along the lines of Residual Current I'd say, they do plenty of industrial work with cable sizes I don't even touch in my worst nightmares 😀 Although technically qualified as a spark I'm more or less a DIYer (i.e. I don't work as a spark, just do my own work) and the biggest cable I've ever worked with was 16 mm2 coarse stranded and 10 mm2 solid. Both tiny compared to this! Living on the more frugal side of 3-phase territory, the largest supply the average domestic spark has to work on is 35 amps per phase and usually 10 mm2. Riser mains in apartment buildings do go up to 35 mm2 but I've managed to avoid that so far. The Germans go up to 63 amps per phase in domestic but are more adventurous in cable rating, so they don't go beyond 16 mm2 either. Austria is very conservative in terms of overcurrent protection when fuses are involved (as opposed to MCBs) and DNOs are even more so. Our DNO will only allow up to 50 amps on a 16 mm2 supply (three-phase, reference method B1 or B2).

Hello Gareth, the DNO are visiting to remove the old 100a supply and dig up the road to tap into the ring of mains from the street for a new 200a loop off into a new service cut out to be installed below the trunking We installed. Because it’s an operating school the new 95mm thermosetting swa supply set has been run in parallel to the old 25mm 100a supply, we would need to be present when UKPN do the switch over on their end so we can switch the cabling on the MCCB and remove the old earthing cable from the MET. Thank you for the feedback

@@maydayelectricalsolutionsl7601 Ahh ok so its only because its running in parallel then? Cheers for that

Hello Michael, the beast east a 95mm 4 core

These where some regular cheap grips nothing super special

No there will be a main mccb protecting my sub mains with the correct selectivity

@@maydayelectricalsolutionsl7601 Short-circuit and fault protection will have to be provided by the DNO fuses though as your MCCB is downstream of the armoured.

The audio works fine not sure why it’s not your end

@@maydayelectricalsolutionsl7601 Yes it works, but only on the left channel. Try listening with headphones

Audio though headphones is fine. Both channels work.. Must be your headphones.

@@Lukieboy2010 now it also does, weird, my headphones are find and worked for every other video i watched, after a reboot this one also seems to work

I’ve had a few comments on that so it’s not something we will use again

@@maydayelectricalsolutionsl7601 yes this is the first time I have watched did not like the jumping of colours just fast forward.

A good point that I’ll consider next time
