I read a short article in this months Professional Electrician about the Kewtech KT63; I'm looking for a cheap, no frills tester which will match the 17th Edition standard, and this looks to fit the bill. Has anyone here used it, and can they recommend it? Thanks

No, no timer. There's a window in the kitchen. The lady likes to make soup and wants manual control of it, so there will be no direct feed; just the switched feed.

I'm just returning to the trade following a happy hiatus of some 15 years. I've just sat and passed my 17th Edition course and H&S. Now I have to get back to reality. I'm pricing a job to install an extractor fan in a kitchen roof. Am I right in assuming that (as I would have done years...

To be fair, the main installation might have per-dated RCD protection. There's no documentation, but my hunch is that the shower was installed within the last 5-10 years; the 45a dp switch doesn't look so old. I just think the spark was lazy. And for me, too, why place an isolator inches from...

Thanks, TS. I just thought it was a bit lazy of the spark. But there doesn't seem to be a defined method.

I've been asked to look at replacing a consumer unit and, while I was having a look at the job, found that the spark who installed the electric shower supply had fitted a 45amp do switch right beside the consumer unit, in turn supplies from the cu by a 45a rewireable fuse. The shower is in the...

@Evans Electric: I think it's TN-C but hard to tell as I don't want to push my luck and break the seal on the enclosure. And, yes, the consumer unit is attached to the enclosure with a brass gland. Hence the reason I really need to break the seals to get the thing off; either that or I'm going...

Hi Technician They are single insulated and look to be about 10mm, let alone 16mm Looking at the green earth sleeving, etc., this installation hasn't been touched for years! Although much of it seems to be in plastic, I found a cupboard light - still working - which is done in lead!! That...

Thanks Technician. But how do you go about things if you can't break the seal. Can you request that the distributor install an isolator? From the picture, the tails go straight from the meter, back into the box and then through a gland-connection straight into the metal consumer unit. The...

Can anyone help. I just recently regraded - after a lapse of some 15 years. Now I'm starting to get a couple of enquiries for jobs, one of which is a rewire. I'll have to install a new consumer unit, replace tails, etc. However, in my day, we would just break the distributors seal and inform...

Thanks for the welcome :-) I got my sjib grade card in 1979 following a four year apprenticeship. I was basically a 'house-basher': domestic work, rewires, light commercial. I wrote to Select and they advised that I required a " ... valid BS 7671 Certificate gained within the last five years...

I'm attempting to return to the trade after a short hiatus of ... erm .... 15 years. I'm informed that, in order to renew my grade card, I have to gain a BS7671 Certificate. Can anyone recommend where I can study this online? Not being too sure of all the new rules and regs, I don't want to...
