Curious about supplementary bonding, I have these two 4mm Cables loose and not connected to anything in my parents house. I presume they are for the hot and cold copper pipes, my questions is do i need to join/make a connection between the hot and cold pipes? I work as an electrical improver...
A few 30mA RCBO's that i have tested recently are tripping lower at x1 than they are at x5, e.g 13.1 x1 13.8 x5, I know both these results comply but im curious does any one know why the 1 times trip is lower than 5?
Good Afternoon All,
So I have a new situation to me that I cannot seem to get a definitive answer for. I trained as an electrician and did several years as an apprentice many years ago now and have since maintained those skills through maintenance of my own home. I have no issues doing really...
Hi all,
For clarity, I'm not a qualified electrician, but have a reasonable amount of experience as I've done plenty of wiring (signed off by a proper sparky) as a farm manager in the UK.
I now have a house in Bulgaria which we bought some five years ago and have been slowly modernising during...
I have my AM2 coming up next week but something is puzzling me and I’m hoping someone can help me out.
So there is some SY cable coming out of the DOL into the 3 phase motor. From my understanding they provide 4 core SY.
I’m a bit confused as to where I’m supposed to get the CPC from as from...
Hi, I'm just a DIY're but I'm OK with basic electrics. Grateful if anyone could help me with the location of where the double resistor is wired to. I had to replace the control panel on the convector side of the heater and decided to also replace the elements as one had stopped working over...
Hello everyone, I have a piece of 110V plant that is not working. The wire from plug to NVR had a partial cut (rectified). The NVR energises so assumed good. The motor has what looks like two capacitors (white and black). I am trying to run some basic checks on the windings (resistance) but...
Hello,
I have a Leviton 51120-1 SPD connected to a residential (120/240V) 200A breaker/service main panel – The 51120 is fed from (2qty) – 20A breakers in the service panel – All wires connected to the 51120 (L1&L2 hot, neut,& ground) are 12 AWG stranded conductors – The install instructions...
hello
soooo...😅 i recently changed all the light switches in my house. now i saw a video that showed the 2 tiny wires inside the switch should be connected to the "in" and "out" thingies. BUT, before installation, i stick them in a power outlet (witch has a phase and a zero obviously 😎) and saw...
I know I'm cheating a bit but I'd put money on it that some of you guys know a bit about plumbing.
Basically, the Shower doesn't get that hot. I don't think it has since the boiler( I'm not 100% this was when) was changed. But the Sink and everywhere else does. They paid to have a new shower...
I was surfing through one of the electrical training groups on Facebook yesterday and came across this question from an AM2 prep course:
There were 4 points to fill in after that.
Initially I thought of the C1-C3 and FI codes, but then thought that these being the codes for EICR wouldn't be...
Question about the Definition of #6 wiring standards for Thailand as of 2023?
I am having a House/Villa built in Thailand and I wanted to wire one room with both 110 & 220 capability? The contractor wrote back and said the cannot provide the 110 volt out let, but that they can wire it with #6...
Was having a look at our gas and electric bills today, and its getting depressing.
I would like to keep using our appliances as and when we want... and apart from working out how to shut off the hot tub overnight.. i've not made any other changes. (will be confirming efficiency by using an...

I want to build a new garage with living accommodation above around 20m in front of the house. The house consumer unit is right at the back of the house, in the middle of the...
Hi fitting a a couple loft sockets on a radial circuit.
I only have 2.5mm cable and really don’t want to buy a reel 4mm2 is it ok to use on 32A mcb if I put a fcu before the sockets as it will never exceed 13A and the cable is rated for 27A.
Or is it better to add another separate 16A breaker...
Hey all,
First post but have read up a lot over the last few months as I have been prepping for my AM2s which I sat last week and thought I done well on,
Good news is that I only failed on 2 sub sections of my install, the ring circuit and the heating system, neither of which are circuits I do...
So, the actual job is on a farm. I think I'll keep things simple at the moment and just ask about voltage drop. I'll come on to earthing and bonding a bit later or on another thread!
We have a 3 phase supply (100A p/phase). From supply to first barn (we'll call it Barn A) is 70 metres. For...
