Hi Biker Mike if you press & hold the " ctrl " bottom down and then use the scroll on the mouse, you will be able to zoom in and out as it were.

Cheers made one on the cheap: double plastic socket box from Wilkinson along with 2 5amp 12 way terminal strip screwed into box.

Ordered the resistors-fitted into the box without the need to cut them.

The parallel resistors soldered them together before fitting them.

Just added blanking plate when not in use.

Great Stuff, Alec.

Any chance of some pics, please Mate?

For RCD reference checking, use a common (the same) socket in your own home (assuming you have RCD protection)..

This ideally should be done after calibration (and on a regular basis)..

Log results in a nice table...

What did you use to hold your connector strip to the pattress Alec? ?:|

 

[Alec]

I think they are Counter sunk 4ba screws with nuts.

 

[extension15]

I suppose any old nut bolt will do..

 

[biker mike]

And u dont have nuts and bolts u could always use "THE FORCE"

Plan B - use a non-RCD socket, and put an RCD in your checkbox.

If you also add a BS1363 socket with a low-ohm resistor (will need to be rated at a couple of '00 W) switchable into the cpc, you can check your loop tester too, in any socket, and irrespective of local Ze variations...
