Hello all I understand that when an RCD protected circuit has only the MCB switched off and thus only the live isolated that when cutting cable a N-E fault would trip the RCD What if the circuit was only protected by an MCB and not an RCD? Isolate the live then if you were to cut the cable and...

Thanks - what’s the limit? 22,000ohms?

Hi all - my plumber recently installed a new wall mounted tap/shower mixer plus some new pipework. A direct replacement basically. In doing so he removed a section of copper pipework (and copper elbows) and replaced the copper pipework but used JG Speedfit elbows. the equipotential bonding...

Evening all Would appreciate some expert advice! I've just replaced our sink and tap with a new 'out the wall' type tap. Having plumbed it all in there appears to be not pressure on the hot water side. If I take out all the pipe work and open up the isolation valve the water doesn't even come...

Hi all Thanks for your time to look at this. In front of my house by the bay window is an area where the wheelie bins are kept and the previous owner had this area (not large, say 4m2) laid with bark chippings. Over the past two years this has got wet, full of weeds, muddy and just looks a...

hi all I have a dishwasher and a washing machine both plugged into a 2G socket directly behind the machines. These plugs are not accessible unless you pull the machine out. An engineer was complaining about this and suggested these had above worktop FCU's. How best to wire two FCU's from...

The cables barely come below the plasterboard so a join within the light fitting wouldn't work. Between the bottom of the joists and the plasterboard is a 50mm void. How could I join the cables within this void? I'll have to cut a hole in the ceiling

thanks - the earth cables are all connected in a block and taped up

hi all In the attached photo you will see my kitchen light wiring. I had the ceiling taken down for sound proofing reasons. It has been put back up but lowered slightly. There is barely any cable left to play with and very little slack so that further cable can't be pulled through. I want to...

Hi all I'm just about to insulate the kitchen ceiling at the weekend with Rockwool slabs. From the picture you can see copper pipes and electrical cable within the ceiling cavity. What is the correct method for insulating around these? to apply the slabs above the cables/pipes or below them...

Thanks for your replies. The flow and return pipes are both hot when the heating is on, the pump is hot also. I turned off all rads apart from the furthest one in the bedroom and this heated up very well - when all the rads are on this bedroom rad doesn't heat up. The diverter valve was a...

Hello all I have a Vaillant Turbomax 824E - when there is a demand for heating everything fires up as it should, after several minutes the heating turns off even though the digital room stat still indicates a demand for heating. The pump overrun remains on for ages afterwards. The rads nearest...

Thanks for this. Can you explain further? From the isolator switch can you explain where the 3C &E should be connected? What new connections do I need to make at both the light and the switch?

Thanks Iggifer, I have no access to the space above as there is another flat above. What's the untidy solution?

Hi all I want to wire up an extractor fan with timer to my bathroom light. I have a 3 pole isolator switch plus three core and earth cable. I have attached photos to show the wiring at the bathroom ceiling light and also at the light pull cord. Could you advise how to wire up the fan based on...

The answer is that it is wired up correctly, I've found the photo I took before it was removed. Time to call a plumber. Thanks

I'm sure you're very knowledgeable, no offense intended (I haven't got a clue) but as you haven't supplied a constructive response to my question the reasonable assumption is that you don't know the answer

I would appreciate any helpful responses, does anyone know if the wiring is correct? That was my original question. The only two people to reply haven't got a clue
