Where do people record the Ze & PFC of a 3 phase installation, if there is say 10m of 25mm tails between the 4 pole isolator (next to the meter) and the 3 phase distribution board, therefore some (though negligible) resistance?
Do you tend to test at the origin, and record that result, or do...
Hi Forum people. First time post here.
I have a pair of semi flush fittings that are currently 10 Halogen capsules per fitting. I want to convert these to LED at 2 watts per capsule. Space is a very limiting factor. Each fitting currently has a round transformer inside. I only have an 80mm...
Hi all. Just a quick one to introduce myself, am 43 and decided to give up the office management job that I never got any satisfaction from to take the plunge. Hoping to go self employed, and have done the Level 2 with Level 3 ongoing. Any advice on how I can get opportunities to work to start...
I have a recessed light over a shower with a 4” glass cover. I broke the glass cover by dropping it :(. Are you able to buy a replacement cover or do you need to buy the entire metal housing and glass that comes with it? I don’t see this at Home Depot or Lowe’s without buying the whole thing...
There is power flowing. I have checked with multimeter. One light on the line works..even replaced the switch it is connected to. Rest of line still down. Been down for months since a large storm although no indications of lightening strike. Replaced breaker on Sunday...no dice. On Tuesday power...
Hi all,
Hoping someone can advise.
I have spent 4 years on an apprenticeship: Level 3 Electrotechnical Qualificaiton (Installation route) (5357-03) - this info just gained from C&G.
I completed all the class work and passed all the exams - so all units are complete on the class learning and...
Over the holiday period my partner returned home to her apartment with no power. None of the internal breakers in the consumer unit had tripped and so she was unsure what to do. She called an electrician who took the cover off the consumer unit and then showed her these singed breakers across...
Hi all. I have noticed there are two schools of thought here when running a separate earth with a SWA to a large DB, where is the correct place to terminate the earth ? . We can go straight in to the internal copper earth bar as we have spare unnumbered holes for it , or we can lug it and go on...
Does any one have a link or know where I can find the diagram I’ve seen that lays out what rcd devices you can and cannot have up/downstream of each other?
e.g. you can’t install a type A downstream of a type AC etc
it was a good little diagram but I can’t seem to find it again, I think it was...
Is it acceptable to run mini trunking as shown in the pic? To my mind it would be safer (and slightly less ugly) to have a drop from each socket and then run it along the top of the skirting. I would be concerned about the trunking coming loose and being more likely to suffer mechanical...
I need one of these today, anyone know who has stock?

Hi Guys
Got an Emmeti UFH manifold box we wired up a while ago, fuse inside has gone 'pop' for some reason.
Not brought this type of fuse before - clear casing, got 4a marking on PCB above.
What do I search for is it a special type ?
Thanks Sy
Hi all,
I've recently had 2 customers enquire about installing a backup generator for their domestic premises.
After a lot of research, contacting generator manufacturers, and generally going around in circles, it's become apparent that TN-S, or "centre tap earth" generators are practically...
So I want to arrange for a 120v a/c plug to be firmly affixed to the wall, such that it won't slip out of the outlet. Cheater plugs have these metal tabs that you can screw into the outlet, but I don't want a cheater! I want a 3-prong grounded plug with such a metal tab that I can firmly affix...
I'll soon be installing a 45A 3 phase deep fat fryer at the school where I work. The run is approximately 7m from the DB, and the cables will be enclosed in empty trunking. What size cables will I need?
