Thankyou for the quick reply . I am not involved in the plumbing just the electrics. I think the boiler just falls into zone3 (abolished under 17th edition!) but thought it safer to put FCU outside the room. Its been awhile since I have seen a boiler put in a bathroom , I thought it was illegal !

Hi, currently working on an extension where the boiler is to be in the bathroom. What are the current regulations regarding electrical connection? I'm thinking FCU outside bathroom and final boiler connection via a flex outlet plate. Is this right?? Cheers Steve

Thanks for the reply. Basically I want to run a new ring circuit round the cellar wall to save disturbing a 'very nice' lounge carpet up above. (customer request) Trunking / conduit is obviously best practice but as always it comes down to cost. The cable run is at head height / along joists...

Is it still permissable to 'clip direct' the cable to the wall in a cellar ? NOt aware of any direct reference in the regs ? P.S. there is no sunlight down here !!

Hope someone can shed light on this one!! Fully rewired a semi and new 100amp supply installed by authority. A circular saw is being used next door which is also being refurbished/rewired. The rewire here is virtually complete except for a couple of customer fittings. When the circular saw...

Why haven't I thought of an angle grinder before :o I have an SDS drill / chisel but it tends to have a mind of its own and puts big holes (sometimes serving hatches :lol: ) in the wall! A couple or more cuts down the brick with a grinder should give the SDS chisel some guidelines? NOW...

Well that caused some head scratching!! :roll: I thought there wasn't enough info on the cooker too ? I will reveal all after next weeks lecture ........ Thanks again to all ...... with the exception of Andrew 2022

I am going for the gas cooker assuming there is no mains connection and is only earthed via the bonding? The transformer would be a 'exposed conductive part' ? Thankyou for your replies.

If said nail goes through cable from enthusiastic DIY you will be very glad a new piece of cable can be pulled through the said conduit ! (Hopefully!)
