test rig - wiring ?

newtothis · Jun 28, 2015

I’ve read searched and read what there is on this forum.

I need to get my testing up to speed so I can do it 2nd nature.
Takes me 50 mins plus to test 4 circuits on a test rig situation - too slow.

I think having test rig with 4-5 circuits would help.

I know how to wire it however I not sure how to connect to the electric .
Specifically what way to connect it so it’s safe and gives realistic readings.
I’d ideally like to easily disconnect this an store out of the way when no in use.

Any advice or comments would be appreciated.

This may seem a daft question but why not use your house as the test rig, no need to put it away when you've finished:whatchutalkingabout

I see what you mean.

The problem is that the one in my house is in a small cupboard under the stairs, therefore a real PITA.

I have to add, I've already tested my house, twice.
So not just being lazy

Does anyone want to share - the wiring particulars, or not ? LOL

What sort of set up do you have on your test rig?

Thanks for you input pete999 I haven't set one up yet, I'm more bothered about how to wire it so I can do the full range of tests.
Would have typical final circuits. Is that what you mean ?

Well I designed some at the place I worked, built on mobile board consisting of a small 4 way CU ( No RCD on the board) as it was mainly used to train indigenous trades people (I worked overseas a great deal of my time so not every country had our type of supply structure).

I guess you could do something similar, my circuits consisted of a Ring Final Circuit, a radial, and a couple of lighting circuits, the CU was fed from a socket (not ideal as you can imagine but it served a purpose)

If you did it that way, and you have RCD protection in your house CU then you may have a problem, unless you have a dedicated socket which is not covered by a RCD.

We used the ZS at the supply socket as the Ze for the test board, and the testing was as normal after that, as I say not an ideal real life scenario, as the circuits in question were a short run, so the Ze and Zs were somewhat similar. it just gave the people in question an ideal of how to test, hope this helps, and I hope I don't get too much stick from the diehards in the forum, good luck.
