Russell griffiths Posted April 2, 2019 Share Posted April 2, 2019 Work out how you are going to board it, and put them in according to your board sizes. 2 Link to comment Share on other sites More sharing options...

Dee J Posted April 2, 2019 Share Posted April 2, 2019 1200 is max height for the lightswitches... if you want to put noggins at 1200 then switches in drywall back boxes can always go lower ? 1 Link to comment Share on other sites More sharing options...

Metal back boxes securely fitted to dedicated noggins (or maybe the recently introduced adjustable metal noggin system) will be neater, more secure and easier to plaster/skim than plastic drywall types.... but need a bit more planning, skill and time to set up and board around. https://www.edwardes.co.uk/en/products/erico-187191-tsgb24-telecopic-screw-gun-stud-box-bracket?utm_medium=google_shopping&utm_source=google&utm_campaign=google_shopping&gclid=Cj0KCQjws5HlBRDIARIsAOomqA1s5_fSsykExl34rmc7ZovqTTDkVOFDzevTVqehQEZb166xnOhdLX4aAqgwEALw_wcB Edited April 3, 2019 by Dee J Added link for adjustable steel noggins.

mvincentd Posted April 3, 2019 Share Posted April 3, 2019 I've just fallen foul of this. I put noggins at 1200 vertical centres on advice of builder, but they stagger with every other one being 1150 to make fixing them with paslode easier...so with 50mm thick noggins the consistent unimpeded height where I can unify top of back box height has resultantly become 1125. Rules say top of switch max 1200, and depending on switch plate thats approx 25mm lower than top of backbox....so my switches have been pushed down 100mm by my noggin strategy. Given i'm boarding 2400 vertically i'm gaining nothing having noggins where they are versus set 100mm higher. Link to comment Share on other sites More sharing options...
HerbJ Posted April 3, 2019 Share Posted April 3, 2019 Something like this? Our electrician installed specific noggins for every back box and support required for the electrical 1st fix - he has more tools than the carpenters! He didn't try to use the noggins in the stud walls that were part of the TF Link to comment Share on other sites More sharing options...
Oz07 Posted April 3, 2019 Share Posted April 3, 2019 Did all 3 switches need to be that close he's hacking your studs. God I hate when plumbers and sparks get saws out Link to comment Share on other sites More sharing options...

The studs were not hacked. The carpentry is better than some carpenters work I have experienced. Link to comment Share on other sites More sharing options...

Studs look plenty chunky enough to take it though. Link to comment Share on other sites More sharing options...

God I hate when plumbers and sparks get saws out Builders, self-builders and diy-ers often bring this upon themselves. Electricians and plumbers often find themselves brought into a fait accompli of structure and studwork where little or no consideration has been given to location of services, and with a limited time and budget for first fix. At least as an electrician I have some options on cable runs. Seen some awful drainage runs where the plumber has been boxed into a near impossible situation. A favourite challenge is the steel entirely filling a void right across the middle of a building with closely spaced timbers either side. Link to comment Share on other sites More sharing options...

Not sure under which circumstances they could cause condensation, I guess if they somehow bridged to a colder part of the structure... Link to comment Share on other sites More sharing options...
