Hi all, quick question. A friend is doing up his house, and was advised by his sparky that they couldnt do any work on the electrics until a fused isolator switch was fitted between meter and CU. I suggested it simply needed to be an isolator switch, as tge fuse would serve no purpose (I have...

Thanks all for responses, although sarcasm not entirely helpful...I took guidance, whether it was out of date or not! Plan is to move the boiler onto the same phase as the remainder of the heating system, which has the added benefit of it being supported by the battery back up in the event of...

thanks all...so something like this should do the job? https://uk.rs-online.com/web/p/non-latching-relays/3863220/

Yes, I could put the boiler on the upstairs phase...but this goes against the advise I was quoted - the boiler service engineer uses the utility room sockets for his testing tools...which would then be on a different phase! But if you guys don't think that is a problem, it would be my quickest...

The house had three phase because it was entirely heated by storage heaters - which all came on at 0100 via a massive 100Amp time switch. Long since gone - but there is also the ability to connect a small generator in the event of power failure, which connects via an isolation switch to one...

Thanks both - I think the (however highly unlikely) scenario is person using hoover on one phase with a fault turns a light switch on with the other hand - and two faults happen at the same time, resulting in a novel earth route. Not sure if feasible, but as you say, the first belt would be a...

Thanks ban-all-sheds. I was advised by my local sparks that having different phases in one room, where potentially someone could connect two phases via their own bodies was not allowed (or at the very least inadvisable) - and I have to say, seems sensible. But he is the expert (or not, as the...

I have a house which has the strangest electrics ever - converted from 3 phase. Originally, it used a three phase board, but lighting circuit, power circuits etc were random - and highly dangerous, because I could have sockets on one phase and lights on another in the same room. I had a sparky...

I did wonder about V blocks - the issue is the movement I will need - the drill is 900mm long. And unfortunately cannot screw to the floor - but I could screw to the wall. There are rigs that will take a diamond bit - they are hung upside down on the wall - but whilst that is possible, getting...

Hi - I need to drill two 22mm holes exactly perpendicular through a very thick (520mm) wall (once external) to meet existing CH supplies. I need to be exact, but these pipes are only 100mm and 130mm above floor height respectively. Does anyone know of a jig or frame that can be bought or hired...

I have serious damp on brick window pillar. Having hacked off the render (clearly been bodged - mix of sand/cement on top of plaster finish in places!), clear that significant damp coming through from external wall. This is the original part of the house, and I believe it has solid walls, or...

All, sorry for delay - been out on business. The need was to reduce the amount of pipe re-work to resolve an issue, but in discussing the problem of a reversing solid fuel boiler with a heating engineer, he thinks we can resolve the problem in a different way. Thanks for all assistance.

I am trying to find a three way diverter which doesn't follow the normal T geometry, ie inlet at the bottom, diverts either left or right. I am looking for inlet at one side, normally open straight through, diverted out of lower outlet when called ie on a standard diverter inlet B, NO outlet A...

Chappers, you are a genius - never even heard of a door trimmer before. Brandon hire do one that will cut to 10mm - perfect. Many thanks.

Thank Diyisfun - well spotted - I am informed that the Mafell KSS300 can cut as close as 11mm - but I really don't want to spend £600! https://www.dm-tools.co.uk/product.php/section//sn/MAFKSS300#.Vq4ahI3FaWw

I am repairing a hardwood floor that has been fitted without any expansion gap which has caused it to bow. My intent is to remove the skirting boards, and take 10-15mm off each edge, and put new skirting board back (this time matched to the rest of the house - doh!) I can do this with a hand...

I have a garden wall which suffers damp, because no drain was placed behind it when it was built. This retains the ground behind my house - only about 3ft tall, but it is the first thing you see when you look out of the window and is unsightly. Currently, top layer render is coming off, or where...

None taken. Its just a gut feeling - getting a 400v belt that cuts out at 30ma doesn't really appeal - have had plenty of 230v belts, but provided there is protection generally been ok. (although shorting live and neutral through your neck as you plaster a ceiling and back into an un-isolated...

Thank you all - your point about 240v being as lethal as 400v is well made. I will provide some warning labels, and have decided that I will run the essential services form one phase (as easy to take the feed from a separate phase than from a separate breaker) which can be isolated and used on...

Having received some excellent advice about the best way to service a small number of individual services form an emergency generator on this forum last week, further investigations have thrown up a question and I am looking for a "best practice" solution. The house has a 3ph supply, presumably...
