consumer unit

Here's my problem: I hope I've isolated the appliance that causes the right hand side of our consumer unit RCD to trip. If we leave the dishwasher on alone we can come home to find the CU has tripped. I flip off the offending circuit (washing machine, tumble dryer, heating boiler, dishwasher)...

Please see attached photo of electricity authority incomer and consumer unit I cannot see an earth cable coming out of the electricity authority incomer cable, nor can I see a main earth terminal on or around consumer unit. Should I direct this to the electricity authority as I can't see an...

Hello My home is 50 years old this year and has never been rewired. In recent times I've noticed that when similar houses sell in my estate they always rewire them before moving in. I presume that rewiring will have been a recommendation on their survey or maybe even a condition of the...

Hello, The house that we have bought has a CU that was last tested in 2016. It has a 100A supply Main Switch and then a single 63A RCD that protects 7 x MCB: 1 x 40A Shower - 10mm Cable 1 x 32A Cooker - 6mm Cable 1 x 32A Ground Floor Ring Main - 2.5mm Cable 1 x 32A First Floor (small) +...

A must watch: Regards: Elliott.

Do MEM still make domestic consumer units and how do they rank against makes like Schneider and Hagger? Also is Eaton and MEM the same brand these days, I had a MEM CU in my old house that was built in 2003. Regards: Elliott.

Hi All, I have a socket in the bathroom which has gone dead. I can tell this is not on a ring main as it only has one set of wires connected to it, could anyone tell me how I would find out whether it is connected directly to the CU or it is a spur off another socket. I was going to open all...

The distance between a new CU and the existing meter will be more than 2m (probably closer to 5m), do I need a trip/isolator between them?

Hi, I've got an old consumer unit in my flat and the light fuse seems to have gone. Can anyone advise how to replace this fuse? Do I need an electrician? Hope not.... Attached photo of fuse box.... Any help appreciated......

Can anyone recommend a consumer units that screwfix stocks? The prices seem to vary from £80-£230? I have a 3 bed end of terrace with the old style fuse box and would like to upgrade. I probably don't need top spec. Thank y'all

First post after getting my first house. So, I've traced the cables round and read up on the regs but I'm going round in circles with checking a few things. Do I need to get somebody in to put these things right before we start to decorate(over the next 5 years!) I would pay for a proper...

Moved into this new house in Dec 2016 , house was built in 2008 - and I notice that although every heating controls (time clock, zone valves, boiler, pump) says protect with DP switch fitted with 3a fuse that the only thing that is protecting the circuit is a SP 10a MCB in the consumer unit...

Hello - just want to double check I am wiring this RCD/RCCB correctly only its only got 'N' stamped on the left hand side. - it is feed/supply from top and Load from bottom isnt it? Thanks.

I noticed today that the mains switch in our CU is a single pole (63a fused) switch (only Live attached) - when did they do away with Double Pole mains switch and wouldnt Double Pole be safer than single pole so that when you turn off the main switch in the CU it kills both live and the neutral...

Hi there. I've got a simple question about isolator switches like this Wylex 100A one. Their datasheet says: "It’s safer because the supply tails are fixed and finalised in a sealed unit – instead of being left hanging loose ready to connect to the meter." but their diagram shows it between...

Hello - my sockets RCD tripped the other day and all sockets upstairs and downstairs went off - all well and good so far - but all the lights in the house were on , and I see in the (GE Euroline) CU that there is only one RCD trip and that is protecting the sockets only - the Lighting Circuit...

Hi, Our current consumer unit is safe and tested, but has a plastic housing and not metal (none flammable) like ideally it should be. Is it possible to just buy a new metal based housing that will slot over my current consumer unit and cover the front, sides, top and bottom, but open at the...

If one's incoming HRC fused cutout was short circuited upstream of the main 60A/80A/100A fuse, is the only other protection the thermal overload on the sub transformer or is there any additional in protection? Do sub transformers have any direct magnetic based overload protection like MCB's do...

Hi, I am trying to disconnect my electric doorbell from the consumer unit. Can I pull out the fuse? I have tried after turning mains off) but it won't come out? (Pic attached) Any help appreciated thanks!

I am going to purchase some high end AV equipment and would like to protect it against unexpected surges (e.g. lightning). What's the best way to do this? I know I could buy something like a belkin surge protector to plug into the wall, which covers 650 joules...
