And the value of this initial starting current is?

Not forgetting the Test lamps and the indepedant source to check the test lamp iaw GS38

And each coil is marked as Red, Yellow, Blue or L1, L2, L3 or X, Y, Z orr similar. But as this only affects 3 phase systems and most households are 1 phase we don't need to wory about the phase identification or at what angle of rotation it is - it doesn't affect your TV or Microwave.

Is this a single or 3 phase installation?

Can we have all of bushynut's questions in one thread please.

Discharge lighting uses a starter to ignite the gasses when switched on. This starter can draw up to 1.8 times the current need to sustain the ignited gas. Flourescent lighiting is classed as discharge lighting so for the calculations of total load then the possible starting current is the...

This is covered by Reg 526-03 Accessibility. If the connection is to be permenantly enclosed(Tiled over) then you must only crimp (as breezer has already stated) or braze,solder, weld or you can use a compound kit. I have seen many a choc block where the conductor has snapped and is only...

Phase (also known as Live)

Seriously though. If you are completing a rewire of a large 2 story building and intend to test the electrical installation do you intend to issue a Electrical installation certificate and associated paper work on completion of the test? Is there a requirement for a signature to say the...

I replaced a CCU the other day. 3 fuseways each had 2 phase conductors yet the flat was only fitted with 2 ring circuits. The 3rd was the lighting cct, who ever had upgraded the wiring in the 70s had run a seperate feed to the light in the lobby where the fuse box was fitted. If you are...

Knowing computers he probably will be. :lol: And mind your head when you stand up

Well I hope he has x-ray vision, otherwise he is going to be ripping up a lot of floorboards and pullind down a lot of plaster etc. Thank heavens I live in Scotland. If all council appointed inspectors are going to have that attitude. :roll:

TraineeSpark stated: Now the phrase states: "or by equivalent mechanical protection sufficient to prevent penetration of the cable by nails, screws and the like" - so why can't we use safeplates http://www.tlc-direct.co.uk/Products/TLSP1.html if they are of a sufficient thickness? The...

So the property owner hasn't informed the LBA as he didn't know he had to (doesn't know about part P) and the contractor asume the property owner has (or isn't interested). So no certification is done. Who is responsible? And as a thought. Who is going to be prepared to certify someone...

Yes, the radiators are bonded to the hot & cold water pipes (metal bath, soil main, electric shower, shaving socket, heater etc if required) unless they are connected using plastic pipes. Onsite Guide has a couple of good pictures.

If the boiler is external to the house and has an electrical supply then it must be outside the equipotential zone. Then any metal pipes (oil supply and water) would need to be bonded. Now the question is - which side of the firesafe does the bonding connection on the oil pipe need to be?
