Just wanted a quick double check on this as a DIY'er I wanted to add another light to the garage, i've had to cut some holes where the rafters are as seen above and below: I've run some twin and earth though to link to existing wiring, plan to notch out the rafters and plug the holes back up with the pieces cut out. Simples? Or am i being a div?
Your not supposed to run cables under the rafters or joists, they should be 50mm from either the top or bottom ie through a hole. Don't notch out underneath, it weakens them. It would have been a lot easier if you had used conduit.
You are not really meant to notch the underside of joists but a little nick out of a rafter for a bit a t&e is probably not going to mean the roof will fall down. I am with Kiab on a nice LED tube. Just one question is the garage integral to the house or is it a flat roof above.
Its a double garage but soon to have a conversion done to make an office/playroom, i cant get to it from above as the bathroom floor is tiled. It was an effort to make as tidy a job as possible. A rethink then perhaps.
Its integral and i wanted to stay away from the tube idea (i did think about that) because of the future conversion.
Could i run a chase along the board, wide enough to get a drill in, drill my holes 50mm up, feed it through then just do another skim of plasterboard over the whole lot? Seems excessive but ticks the boxes?
Why do you want to make life hard for yourself? Just do it in placky conduit. It's hardly needs to look "nice" for an office/games room.
I was actually expecting the ceiling to be double skimmed with board, its not, so i might as well get it done and sort the lights properly. Being integral to the house it will also help to deaden any noise. Thanks chaps.
I would have gone between two rafters, fed a small drill up there and put a 12 or 15 mm hole on the centre line of the rafter each side, then thread the cable through. You may know te cable is in small rebates, but what about anyone else?
Just done lighting in my own garage. Two 4ft led batten whatjumacallits from Wickes Does a great job.
Yep, i'll crack on with this later, i have spare board to fill the gap. i'll get this done then when it comes to the conversion (when i get around to it) i'll put another layer of fire board up. \o/ Should save me a shock when i plough in a load of dry wall screws for the 2nd layer.
Cut a 210mm hole in ceiling board between joists, insert a 225mm round flat 18w LED & connect to light bulb rose with 1mm twin cable.. (Obviously, check hole sizes before cutting).
That will have to do, quick skim over, shouldn't look any worse than it is already, i'll connect it up when i have a bit of light tomorrow Thanks for info's peeps
Should be fire rated pink board if its a garage, is the original not? but if its being converted to a standard room then probably doesn't matter.
