What does an electrical inspection entail?

Years ago, I did this on a stainless steel sink by drilling a hole in teh side (the vertical part) in an inconspicuous corner. I then crimped a tag to the earth cable and bolted it on, using said hole. This was done inside, so only the bolt head was visible outside.

Another way is to use the type of earth clamps made for connecting to thin metal sections, such as Eze-earth - shown here as type TZB100:

or a Screwfix equivalent: .

Thanks - in fact I already have some of the Screwfix ones; however there's no suitable rib or edge that I can see where I could fit one of these. Even so, I was looking at one and couldn't work out how I would attach the cable even to these! The screw terminal is tiny - certainly compared with the h/d screw on a conventional pipe earth clamp. Is the answer that you have to crimp on a tag, as suggested by Bob above? If so I guess I need a crimping tool, then...

Yes, _everybody_ needs a crimp tool. Get a decent one and you'll wonder how you ever managed without it.

If you get a red blue and yellow terminal crimp tool, avoid the very cheap non cantilever types. Ratchet ones can be bought for under 15 quid and do the job properly.
