New CU Fitted a few teething Issues to sort.

[KRIS537]

Had a new CU fitted at the weekend. But there where a few teething issues to sort out.

First one was the garage kept tripping the electrics out, so the electrican put it on a none RCD protected curcuit. This not an issue for me atm as im having that redone at some point as a workshop.

The main one was the Immersion hot water cylinder. First off the feed to this also powers the boiler but is only a 1.5mm cable. He says thats fine for a boiler but not an Immersion. so im going to have a 2.5mm cable fitted soon as a seperate feed. The issue I have is the MCB trips every so often, but the RCD doesnt. What could be causing this issue?

You're missing something. Properley rated MCBs for a start. A qualified electrician aswell possibly? Daz

God I wish I was a perfect as you!

Didn't say I was perfect so don't be a knxb

I'm suggesing that you aren't being honest, and I'm yet to be convinced you are.

On the continent it is normal to see immersions fed from plug top and lets face it we have the best plug top in the world so can understand the comments on this tread. But saying that it would not be the way I would wire it.

until about 12 months ago my own immersion heater was wired via a plug/socket. Worked fine but then it wasn't fused by a 6A MCB... :lol:

well, having seen plugs welded into sockets on just 2kW kettles, either their calculations are wrong, or sockets compliant with BS1362 just ain't.

Not to mention the fact that DIY Charlies will save a few pence by buying un switched sockets and repeatedly drag the plug out when it is under load and this definitely wont do the plug any good. Again it may be acceptable under the "Regs" but how many times do i say that common sense takes precedence over the regs.
