I'lle be very quite from now on... promise p.s. thanks man appreciatte the time taken Mike

so a bulkhead of class 2 manufactor is put on a wall fed by say single core cables in high impact PVC conduit. The bulkhead being double insulated(?), and not connected to any conductive parts is ok? so what happens if say you brake the casing and cause a possible fault between P and N, without...

Class 2 Equipment what are the benefits? I know it sounds a little silly, but really what are they? Thanks in Advance

thanks man

A soft test is when your attempting to do an Earth Fault Loop Impedance Test and the Rcd keeps tripping before the measurement can be taken, hence you do a Soft test! Soft Test - A low test current (15mA) should be applied for 2S, this will then give the Earth Fault Loop Impedance Test...

Am I rite in that a 25V socket outlet (BS EN 60309-2 25V) is Violet in colour? Thanks in Advance

I'm doing the electrics for my garage which is going to be supplied with a TT system. The reason I'm asking these questions is I want to be able to talk the lingo with the sparky when he comes on site. Sad I know but it the only way of understanding the job being done. I got an OSG and I have...

Just been reading the OSG, can someone pleae tell me why I the RCS IS Unsuitable as the main Isolator/ Disconector. Is it due to it just monitoring the earth fault loop impedance, and protecting against Direct Contact. i.e. if you wanted to test the installation and Rcd will only isolate...

The name of the test, and the details I've listed below are they correct in how to test an RCD Thanks in Advance

Other than the old button test can someone point it out to me that is the name of the test. Tell me if I'm wrong but you test at x0.5 x1, x5, to test that the RCD is working fine? I know the load must be disconnected and the earth loop impedance must also be known. And that a TT systems...

I want to buy a 25v isolating transformer to power a inspection lamp thats going to be used in an inspection pit in my garage. I'm going to spur off the local ring main with a 3A Fused switch spur, all I need now is where I can get the transformer and socket can anyone help, please. Thanks in...

So a 24v transformer will power a 25v Lamp Holder (60W Lamp), with out any problems? I will spur it off the Socket ring in the garage what size fuse should I use? Hey and guys thanks for helping

a 60w lamp is in the lamp So I could just spur the power to the transformer off the lighting ciruit (switch fused with dp switch) inside of the Inspection pit making sure that the socket(SELV) feed from the transformer is seperated from the lighting circuit in the pit Would that be ok, or...

to be honest I don't know, I don't know what size transformer I need, its purely for the lamp holder and thats it. I've tried to research it on the net, but I am coming up stumped. All I know is that I know what type of socket (Violet in colour) I need, what going to be used with it the lamp...

Hi I'm instaling a socket outlet in my garage (inspection pit) for a 25v hand lamp. The socket is to a bs en 60309-2 now I'm going to use a violet one, using the below link: http://imagehost.darkernet.co.uk/i/Ceeform.gif What I need to know is the transformer I'm using is a step down one...

Can the lighting circuit and socket circuit share the same conduit until the circuits reaches a 'T' box where they seperate. 'T' box to the transformer and the lighting circuit to the switch Thanks in Advance

Both my cars are in the garage, a ford cortina and an old triumph aclaim, don't ask why. These cars as you can imagine are being done up, so leakages of liquid is in inevitible In the inspection pit the bulkheads for the lighting are class II with the conduit (steel/ galvanised/ black enamel)...

I work away and my brother will be using the garage as a temporary place of work. All I want to do is when the house isn't being occupied is that if there is any flooding in the area that it won't effect the lighting and socket outlet within the pit. I will have a couple of gerry cans full...

So what would the garage be classed as then? The garage is going to have by the way a 6 way DB (TT) with 30mA RCD. 1 x 32A MCB for the Final ring circuit 1 x 6A mcb for the lighting 1 x 6A MCB for the lighting to the pit 1 x 32A MCB feeding a step down isolating transformer for...

I'm abouts to dig an inspection pit into the floor of garage (only 1 metre deep), I know about the need for shuttering and then cementing the pit. But my main concern is damp creaping up from under the pit into the pit any ideas how I can insulate it to avoid this happening. Sounds silly I...
