Hi all.
We have a 120v 20 amp circuit to an accessory dwelling with a run of about 75' of direct bury #12. The breaker keeps tripping even when there is nothing connected to the circuit. What I've done so far:
Checked all connections in the circuit(outlets, etc)
Then, disconnected the...
The big stately home I’ve been working in has an EMS 5096 alarm system with over 100 detectors and 3 (that I know of) panels.
All detectors are battery powered and radio back to its closest panel. All panels are also radio linked together.
They get the odd fault code which is usually a flat...
This for an apprentice

What is it.
Hi, my CDA FWC303 wine fridge is knackered. The compressor doesn't start and I've traced it to the PTC which I plan to replace and have identified the required spare part.
However, the thermal overload protector has a continuity reading of 3.2 ohms between terminals which although still pretty...
Please advise what I should test / check next.

Hi all,
Gone to look at a intermittent ground floor sockets fault today, the RCBO was tripping at random times with no pattern.
Nailed down a potential leg between 2 sockets ( 0.01 ohms on IR test) and temporarily replaced it to get the radial circuit (2.5mm on 20a B curve) to get it back on...
Hi all
Was looking in to the adibatic equasion as our company will not let us add on to a Ring circuit with 1mm cpc..
I want to give some evidence as to why it may not be an issue.
My question is;
If the circuit is protected by an rcd can I replace fault current in the adibatic equasion with...
So earlier this year I obtained a large machine with a couple of 3 phase motors in it, and the rest single phase. I bought a VFD, correctly wired it up, and while the machine ran with some functions, it also reported "undervolt at source"
I had bought a VFD with a maximum output of 380 volts...
I don't "do" solar, but I've been asked to comment on an aspect of a new domestic solar installation by others.
There is no overload or fault protection, except for the service cut-out fuse (unknown size, assume 80A). TN-C-S.
Installation is as follows (have only seen a photo of part of it...

Hi All,
I understand the requirement for PEN fault detection on EV chargers for TN-C-S installs (or to place an earth rod). However, when I was looking for something else entirely I came across this single-phase 100A PEN fault detector. What would be the use case for this? Would you ever need...

Hello,
My house has 25mm back boxes throughout, but I’ve noticed the previous owner has installed sockets and switches that seem to suggest/specify 35mm minimum. The sockets and switches do still fit flush on the wall, just that it is incredibly tight behind so the wiring has been routed...
