Why are proving units so expensive?

[SJD]

Apart from the cost, some proving units are not well designed. I've got a Kewtech one, and my AVI probe tips won't fit into the proving unit holes, if I keep the guards on the AVI and just have 2mm tips exposed. So I end up using the AVI with much larger exposed tips (10 to 15mm), well beyond what GS38 would have us use. I think it should be possible to design a much better proving unit at a much cheaper price.

Proving on the incomer is no good when there is no supply on the incomer.​

then normally i would be happy to work unaided if there was no supply!

I know I will get slapped wrists for this but I have got into the habit of testing for dead with my voltage indicator then double check with my voltage stick(non contact type). At least I can wave my voltage stick around the tails to check it is still working. Something I cannot do with a VI if the isolator/meter is sealed.

I reckon proving units are so expensive purely because they don't sell enough of them to get economies of scale!

Yes but how do you know if there's no supply?

they should at least be 20% cheaper imo. they should be vat exempt

I remember when VAT was first introduced & my old gaffer was having a rant about it: "Value added tax?? .... it adds nothing to the value of anything, it only adds tot he price .... it should be called Price Added Tax !!!"

And there was two different rates wasn't there? One was 8% I think, but not sure what the other rate was, but it was higher. I seem to remember the lower rate being applied to the toys that you put in budgies cages if it didn't have a mirror, but the higher rate applied if it did. (something like that anyway)

Yes, that would be a good indication.
