Metal flush boxes

[chocolate]

Does anyone know a tried and tested way of fixing a metal flush back box into a brick wall that has been completely mashed ( rather than a tidy bit of knocking out ) by a non-electrical tradesman ??????

Unfortunately, what remains of the surrounding brickwork is in no way secure enough to be drilled for a fixing.

I have a disheartened customer at the moment . . . .

well if you insulate the floors why didnt you double insulate everything??

I mean for goodness sake man what you thinking about!!! No double insulation with all equipment placed out of reach behind barriers and IPX9 with tamperproof screws and all cuircuits protected by 10ma RCBOS with monitoring systems in place with a fully trained competent person ready 24-7. Its the way forward mark my words!.








The above statement only true if i am not paying!!!

i make sure my clients wear steel toe cap insulating wellies....

good practice in my opinion...



btw..should i bond those?

bonding is possibly a bad idea as it may impede motion dont want to be carried away. However attatching a trailing lead from there wellies may be an option

Sorry to interrupt the 'bonding of back boxes' discussion, I found the quick-drying sand/cement . . . . too fast in setting to get a good job done. I tried normal sand/cement mix . . . loads of time to do the filling in well enough to please the customer, and even more time to leave it standing in the bucket for the next socket box to be refixed.

Didn't try the plaster bonding . . . bought a bag though just in case.

Oh . . . I thought it wasn't good practice to take a cpc to the box first before the socket.

Once you realise you only mix a little at a time and use it quickly it's allright. Mind you, if you have a lot to do waiting for the stuff to set, may not be an issue.

top tip ,buy a bag of bonding adhesive ,the stuff they use to bond plaster board to block walls.
i use "lafarge" its white & sticks like **** to a blanket.
rip open top of bag and dump in yer shed/garage.
when its matured enough ie had a bit of damp it will go off solid in about half an hour which is ideal for setting boxes in crappy walls & hollow blocks.
to think i ****ed about for years with sand and cement waiting forever for it to dry.

earth tail from socket to box lug good practice

If it goes off that quickly it sounds good. - and only cost the same as plaster!

yep sets in 3hrs fresh out the bag or 30mins to an hour max depending on how long its been out in the open maturing.
time is money.

A touch of dirty (cementy) water or a little cement in the bonding makes it go off much quicker!
