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 have a camper everything was fine until one night a few weeks ago all the power stopped working for no reason at all nothing changed in the camper but the power just stopped working. I had lent out my multi meter and had gotten it back shorted out, I did not know at first that it was shorted...
Hi all.
Looking to buy a house where the rear of the house is the rear boundary, onto council owned land (a footpath).
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...
After my previous post.... just covering my @ss as have a large refurb coming up! 250m footprint.

I have a run of conduit 172ft from a 12x12 box which branches out to parking equipment with runs about 50ft from the box. My voltage drop calc requires me to run #10s to the 12x12 box. My question is from that box can I size down to the respected size of wire my machines need (#14awg) to branch...
There is a lightning rod on the house. But is it safe to use? Lightning can cause damage to, for example, a tree, destroying it completely. It's not stupid to attract lightning to a house with a lightning rod. In addition, the power of the lightning is so great that it is unlikely to be...
I guess there are a thousand question like this, but I couldn't quite get if I can do this myself or need an electrician.
I have a garage separated from the house that has it's own supply (a big armoured cable that comes from the house) that goes into a 10A RCBO (exactly this guy: GE DP100...
Hi, a few months ago this fan was installed in my bathroom, but it seems to be less effective than the previous one. The humidity setting is meant to be adjustable from 50% to 95% (i.e. it will come on either at a low or high level of humidity). Can anyone tell my where the arrow has to point to...
Hi all,
Probs a simple one here but when testing a 3 phase board for ze as part of a periodic inspection plus part initial verification of a small db supplied by this board should I note the main 3 phase ze within the supply parameters section of cert and then the small db as zdb within the...
