reference methods??

[samthespark123]

hi,

i am putting in a 95000w shower, the cable will be run in a stud wall and then clipped to a joist in the loft but what refernce method would this be classed as would it be either 101 or 102 depending if cable touches wall?? im not sure if thats right.

Cheers sam

95000W eh.....thats a big un!

Always use the worst case factor for any calcs.

Methods 100 -103 are to do with walls and ceilings with thermal insulation. 102 touching inner surface of a wall. 103 not touching inner surface of wall.

you could avoid the thermal insulation and use method C or B

Is there insulation in the stud wall?
I'm with martysparky though use trunking/conduit in the wall and clip above 280mm in loft for insulation method C or B.

 

[martysparky]

I would use a board along the A frame in loft to clip too and move the insulation to create a void to pass the cable.

i dont think that there is insulation, and i would prefer to use conduit but i canot get acess to put any in. i wanted to just make sure that it would be okay to drop the cable down the wall to th ccu and then above the wall which takes me into the loft clip the cable direct to a joist. but for the cable calc what would it be reference method wise bcoz i dont think that the wall has insulation in it and the cable woulndt be clipped direct in the wall due to acess same with conduit and trunking ??

Insulation could be laid at a later date so you should take that in to the equation.

sounds more like a rocket ship than a shower 95kw.
