query on joists from a nooby

[justanoob]

Hi All,
I have only just about to qualify to be a sparky but still a few things a need to ask about as my tutor may have been just a robot and when it come to ans questions he seemed to have no idea. so anyway he mentioned that holes in a joist need to be 50mm from top and bottom but he said if the joist is not big enough than you can buy these steel plates that just knock on but i cant seem to find any on the net anywhere. so was wondering if someone has ever heard of these. thank you in advance.

Why wouldn't your joist be big enough, you won't find a floor joist any smaller than 7 by 2 in normal circumstances, maybe when you come across old buildings but I would tackle that when it arises, I wouldn't spend too long looking for them

Around my way there are loads and loads, go through stacks of steel plates on rewires. You have to either drill too close to the ceiling or the floorboards. If working from above I just drill through 5cm (ish) from the ceiling and pop a steel protector on. I'd never, ever notch out though. Never have, never will.

i dont cut notches in neither i just simply asked if these plates are ok if there is not 50mm from either side when i put an hole in the joist are the plates ok under regs etc etc. not nitpicking about the wording i use if i was asking on my punctuation and grammer then i would use an appropriate forum not an electricians forum. cheers

Electricians are allowed to speak properly too, you know....
