It is a 32A MCB in a consumer unit, with a ELCB/RCD located in the outbuilding.

I'm afraid so, I spent time removing all the sockets and tracing the cables with a meter. It is definitely a ring, I don't understand ring final though. The outbuilding is as old as the main house and was extended around 35 years ago (before I lived there) From the location of wires/sockets...

Power is provided via an armoured cable from the main building on a sperate (alongside the main house consumer unit)consumer unit located in the main house. This consumer unit is fed straight from the house feed (NOT via the main house consumer unit) via 100A connector blocks. The outhouse...

I don't know offhand but the wiring is probably as old as the extension which is approx 35 years (extension is to the outbuilding, the original outbuilding is as old as the main house). The cable is Red and Black. So I suspect the earth will not be 1.5mm (did it used to be 1.0mm?) The...

Hello I have found the sockets ring (in an out-building) is half wired with 1.5mm T+E instead of the correct 2.5mm. The cables are behind dry lined plasterboard, in front of the blockwork. I am trying to rectify the situation with a minimal collateral damage as possible. I have managed to...

Thanks very much, I can stop stressing now and carry on :)

Hello I am building a metal stud wall to divide a room down into two spaces. Most forums online recommend trying to use metal backboxes for the electrics - these seem to always focus on wood stud walls. Since I have no noggins to attach my backboxes to, my thought is to use plasterboard...

Ahh - I didn't know it was a part of the boiler. OK - ill try cleaning up what I have and a soft copper olive with jointing paste - thanks for your help. (y)

Hello - it's not leaking from the boiler end - it's leaking from the compression olive at the exit end - the pipe is corroded and pitted, so I don't think a new olive will solve the problem.

Hello My filling loop started leaking from a bent connector (not the filling loop itself). It looks a bit like a 15mm tap connector but the end is flat like a flange, I've not been able to find one in B&Q, please can someone help me to ID it so I can order a replacement? I have attached an...

Hello: My daughter has a bay window, in which she wants a window seat with two cupboard doors on the front. My current idea is use a sheet material and cut the holes for the cupboard doors, when I've hung the doors I plan to use mouldings around the edges to make them look more like doors...

Geoff: Thanks for your response - There is currently a set of metal shelves you find in sheds up there, they are sat on the floor, but also fixed to the wall. The wall is the divider between our attic and the neighbours attic, it is brick all the way to the foundation as it is the dividing wall...

Hello: I have an attic space constructed from rafters, as opposed to pre-built frames (roofing trusses). It is a pitched hipped roof on a semi. There is a big beam (12") forming the peak, and big beams also about 1/3rd then again about 2/3rds down the roof, these have rafters on them going...

Hello: Thanks for the help so far. I've checked the vessel more - lots of water came out of it, not just a bit, so I don't think it's moisture. I did try to recharge it according to the guide from this site, but could hear air escaping into the system and the pump auto vent started venting, so...

Hello: The expansion vessel on my central heating is faulty - the water pressure is all over the place when heating and it keeps opening the pressure release valve. I went to re-charge the expansion vessel but water came out of the air valve, indicating the bladder has failed. The boiler is in...

I'm afriad I dont know, it's run by a water pump that shuts off when an internal pressure is reached. I estimate it's around 1.5 - 2 bar. The cold feed goes straight into the tank bottom (with a branch off for the TMV) and hot draw from the top - the same as a house hot water cylinder but...

Hello: I have just fitted a thermostatic mixing valve to the water system on my yacht, this is the first time I have used one. It is not working however, when you open the hot water tap warm water comes out for around a second, then it goes cold and stays cold. Closing the tap and waiting a...

Further testing: I have brought the element home and wired it up to a plug with a RCD. I suspect it is earthing through the water, I dipped it in a sink (earthed) of water (obviously not the terminals) and it tripped the RCD twice on the run. Then I did the same test in a pyrex jar (i.e...

Unfortunately it's a non-standard size fitting, the thread is 1 1/4" and difficult to find = expensive, I managed to source one at around £130 delivered. Which is frustrating because a big powerful one is about £35, the non-standard fitting pushes the price up really high. It was measured...

Hello, please can someone help. I have a small (1KW) immersion heater on a boat in a small heating tank (20litres). None of the immersion system is earthed because eathing the electrics on board messes up the electroysis with the metal that sits in the water (prop shaft, eathing shoe etc)...
