I have never TT'd a shed/garage I always just extend the earth from the house.
In the example of a shed/garage being supplied with SWA is the armour of the SWA earthed by the house (lets say TNCS) or by the earth rod?
Also, if the SWA is earthed by the TNCS then you have both TNCS and TT...
Got sent this from a mate of mine working on the job concerned that the electricians first fix on a kitchen was a bit rough. Never seen anything like it me! thought it was a Pi$$ take at first :eek::eek:... (using the term electrician very loosely o_O)
Thought I'd share with you all :)
Hi all , i love these forums , full of semi like minded guys with different opinions etc, so thank you
what I'm after is a course that can be mainly undertaken in my own time and not need to sit in a class room , that will possibly actually have some value with commercial type work
Just recently I have had my interest in electrical work re-awakened because I have a grandson halfway through his apprenticeship and I asked me for help.
The electrical technology was OK as very little of that has changed, but BS 7671 was new to me and so I got stuck into it. I...
short and simple, wifi hub downstairs with weak signal reaching the 3rd floor.
I have not used a booster that utilizes the final socket circuit cabling before, are they any good or would anyone recommend something else?
Well I got spoiled rotten this year, we all know the older we get the presents get smaller and worse year after year.
So Mrs Gmes and I said this year we would make a bit more effort and it worked out ok, I will kick off with some of mine which may not be everyone's idea of a good list but it...
Hi, on my mains I seem to be getting huge variations from the normal 50hz for several minutes at a time. It goes down to 48hz then back to 50-51hz and then will then jump from 51hz sometimes to 65hz but usually hover around 53-57hz for around 2 minutes at a time.
This happens fairly often, what...
I'm Lee, live in Chesterfield and "qualified" with my 17th, Part P, and 2392/94/95 last year after completing a much -panned four week course. Yes I've read other forums, comments about such courses and yes i'm the product of one. Doesn't make me a bad person does it?
Was it easy - NO...
Any one come across a waterproof IP65 or similar replacement for a standard 2way switch in a 35mm recessed back box?
Ive been looking around but have come up blank.
Its a finished and tiled internal wall, and furniture makes its unacceotable to have the added depth of a surface IP switch.
Came across a scenario today where the consumer unit had no main switch. It was a split load dual rcd board on tt installation. The incoming tails had been taken into one rcd, and connected in parrellel over to the other. There is a double pole isolator right next to the board, but nothing...
Excuse the ignorance (and laziness), but what's the lowest watt (equivalent) you can actually pick up?
Want to put a perimeter of downlights in to use instead of lamps so obviously want reasonably dim lights without actually fitting a dimmer.
My latest annoyance is this joiner I am doing work for, he is throwing a fair bit of work my way so can't complain on that score but I am getting really annoyed at his lack of consideration for my part of the job. Went up to start wiring an extension last week and, not for the first time all...
Much though I don't like it, once in a while I use a second hand MCB - for one that has long since gone obsolete and new ones are unavailable. What about testing used MCBs before reusing them, does anyone actually do this?
I just tested a 5A MCB at a couple of values of loading, it seemed to...
