What type of cable enters and supplys the Garage CU? is it black & round (armoured)? Can you look at the cable's sheath and find the size of the conductors printed on there? As others have said, a spur from the ring final is ok (so long as there is an RCD somewhere along the line - at the...

:shock: ... :) :D :lol:

The 2x2.5mm is rated to take the 32A that can flow before the MCB trips so it shouldn't burn your house down anytime soon... But as Qed says it is against several regulations, is bad practice and would fail a Periodical Inspection!

Fair point Andy but I just don't like my body 'completing the circuit'. I use my voltage indicator almost every day (Fluke T100) so there is a fair possibility that a faulty neon would eventually catch me out over the years (even just a slight belt wouldn't be very nice!). For the DIY'er, the...

Good link swelec - like many before me have said - Bin the Neon! The reasons have been well covered in the above link!

I see your point but they may not have both worked loose at the same time - the pins of the socket add extra resistance (they may have been dirty) which would have added more heat at the socket end - the MCB also has a more rhobust terminal connection... Then again, like you say, it may...

A heater takes quite a high load through a socket. If you have been repeatedly using the same socket then the drawing of this current heats up the copper which then cools and contracts once the heater if turned off. This repeated expansion/contraction can work conductors loose!

If you are just installing the boiler then for convenience sake it is fine to take a fused spur off of the ring. If you are doing a complete rewire then I would put it on a B20 MCB protected 2.5mm Radial on the Non-RCD protected side of the DB. This will slightly lessen the loading of your...

When rewiring a ring, I go from socket to socket in the order i'm putting them on the ring, doing as many as I can in one day - I usually have the DB fitted near the start of the job so that I can leave the remains of the old ring on a B20 MCB and the new part of the ring on another B20 thus...

Crafty, I read these forums fairly regularly (don't say much though!) and have to say i'm surprised you are not (yet) an electrician!. Your advice is very good - you'd do well in the trade!

If you're trying to 'future proof' then type 'CAT 6' into google! Edit: Also when running 230v & Cat 5e I have always used a 50mm minimum distance apart rule of thumb - it has never caused me any problems!

Sorry to jump in but just wanted to say to trainee - I qualified fairly recently when electrical work in my area was very thin on the ground - as qed says you may have to work for free at first. It's all about not giving up after the 100th company has told you 'we're not looking to take...

Seeing lighting circuits taken from mains (and sadly vice-versa) is a common situation which most people would be looking out for. A socket off of the shower circuit is more unusual! Safe isolation should always be carried out but in the real world where people make human errors in a rush, it is...

Sorry have to agree with QED on this - very bad practice and could be dangerous - if somebody turns off the 'upstairs sockets' and doesn't confirm each socket is de-energised then they could inavertantly work on this socket. Even if you label the socket somebody could replace with a new socket...

That's AC or 120v DC!

I tried some CK screwdrivers a few years back... still using them now! Good tools for day in, day out use!

Not quite - the problem here is the 'T' that branches to each bank would need a Junction Box! Run the cable from the switch JB to the left light of bank 1 and then along It (as you were) and then from the right light of bank one to the left light of bank two. Now connect across bank two (as...

If you mean you want to run power to an accessible JB, run the switch line from this JB and then daisy chain all of the lights from this JB it sounds fine!

By 'daisy chaining' them together, the phase and neutral is unbroken between all lights (connected at each light) and they are connected in parallel so one bulb blowing wont take them all out Also if you use joint boxes and the installation is inspected later this may be picked up as all...

Firstly the bottom three sockets are wired in a ring final formation - the cable runs to the first socket and then to each socket and then back to the origin. This is a perfectly legitimate arrangement The best way of doing what you are proposing is to break this three socket ring and...
