Hi guys, before starting this thread I have searched old threads on this site and had no luck finding a good one. I started a thread a few weeks a go my house rewire and now im after a bit of advice on filling chases.
I rarely do domestic electrical work so have barely touched on chasing, the jobs that i have done/been on in the past involving chases have been done by labourers.
im going to chase in oval conduits and would appreciate advice on how you guys fix the conduits in before filling, a colleague of mine says he pins in the conduits using nails to hold the conduit before filling with a sandy concrete mix leaving 3mm for skimming after. Does this sound good?
as far as chasing the drops im either going to borrow a wall chaser if i can or use a grinder with diamond disks and scutch out the center.
to cut out the boxes im going to use a grinder to cut the square and chisel out the centers by hand after fixing the metal backboxes and running in the conduits i plan to fill the chases and cuts with a concrete mix with 1 part sand to 3 parts concrete and leave the 3mm gap for skimming over.
a few things im wonderingn are first of all is there anything wrong with anything ive said and also what cables will fit down a flat 20mm conduit? im guessing i need 25mm drops for the 2 2.5mm twins for the rings
thanks in advance guys
