Can I lay SWA (coming from CU in boiler room) in a service gulley rather than burying it?? When I say service gulley I am thinking of the type of gulley with a grate over the top that you sometimes see.
If not can I use large diameter ducting that I stand a chance of pulling cable through at a later date??
