I am renovating my house. Regulations BS7671 apply though my house is not in UK.
The building's electrical supply is provided by three phase cables running externally and fixed to brackets at the top of the building. My local electricity provider has asked me install:
- trunking running down the face of the building to a junction box at ground level
- a galvanized steel pipe (sleeve) running underground from the junction box to the meter which will be located in the under-stairs cupboard next to the main distribution board
I propose putting the steel pipe in the concrete slab next to my neighbor's party wall. This will avoid the need to perforate the new damp proof membrane / course as the pipe enters/exits the ground.
Does BS7671 allow such a galvanized steel pipe? Are there better alternatives? What advice would you give about the steel pipe or trunking.
thanks in advance
