I can’t decide which flooring option is best for a 5m x 3m log cabin I have built. The cabin is laid on a 15cm thick concrete pad but the pad has a deviation of 10mm in places. There’s a bit of a hump in the middle as it chucked it down with rain as it was being poured and I didn’t get it...

thanks. Re: reducing the 40Amp to 6Amp, I just thought perhaps it was best to limit the Ampage on the circuit for safety ( at source). I happened to have a 6Amp MCB I could use. I was thinking of an FCU, couldn't remember the name! Thanks for the help.

My plumber is redoing my bathroom and has requested that I arrange for a 3amp spur to be available for the installation of a Digital HP/Combi Shower. I have two options but not sure which is the best one to choose. 1. When the old electric shower is removed, I replace the 40Amp MCB with a...

If I were to clip the cables to the rafters I would have to bury the cables inside the insulation board? I plan to plasterboard over the rafters eventually to create a sealed loft room so trunking may look unsightly. Thanks for the response, I am going to get a local sparky out to take a look I...

Can anyone please advise if it is acceptable to run a lighting circuit cable between Rafter Insulation Board and the Sarking Felt (1960s Bitumen type)? I have installed 75mm Ecotherm board between the rafters (which are standard 100mm) leaving a 25mm gap. I am considering running a 1.5mm...

Thanks that does help. I am getting some more quotes

Hi I have a quote to install approximately 12 5x2 joists into my loft space including covering with 18mm chipboard. The joists are to be hung from existing binders. The floor is part of a 'loft space' conversion. So no formal loft conversion. I have costed the material at approx...

yes on looking at it again it has a 40A MCB and the 63A 30ma RCD. So I have been giving duff info! apologies

Yes it is one of those in the link

as the CU had run out of spare MCBs a previous electrician had added a separate unit along side the CU. One MCB rated to 63A and a 30ma RCD next to it ( from what I can tell) not entirely sure what im looking at. getting a sparky in anyways.

to be honest I didn't think about it until you said it was a problem. from a bit of research max amperage of 6mm cable is 40A? The Consumer Unit is pretty old, im gonna get an electrician in to replace it as that way i should get a full audit /certification done on the wiring. cheers for...

time to call in the electrician then! thanks for the guidance

Only reason I am considering it is because the electrics in the house were pretty dodgy when I bought the place. Cables pushed into the joist notches against CH Pipes ( they had started to melt). Unless I rip down the boxing around the waste pipe I have no way of knowing if the shower cable...

I have not considered the current carrying capacity. The shower is an 8.5kW MCB is 63A with 30ma RCD Cable is 6.0mm.

I am redoing my bathroom that currently has the shower electrical feed routing up through the floor boards, loose along the underside of the bath and into the loft through the waste pipe boxing. As this also houses the hot water feed from the boiler in the loft I don't think its the best...

well his quote would read "i will need a suitable power point to be provided in the loft space before I commence work" I would guess..

ok thanks for the advice. The plumber said he would need to get an electrician in to put the power in. I don't want to have to pay out for a sparky for something I can do myself (with a little guidance)

Plumbers take on it was "I just need a plug socket" My other option of course is taking a fused spur off the electric shower feed but not convinced thats the best option

well when I say its running off the lighting circuit now, its wired direct into the same MCB as the lighting circuit. Moving it to further along the circuit wouldn't cause any load issues as its only a boiler?

My current boiler has power supplied from the Lighting Circuit. I am having a new combi fitted in the loft, is it enough to take a fused spur off the lighting circuit? Im guessing its not to code? Would I be better taking a fused spur off the ring main and into the loft?
