Semi detached, garden wall at right angles to the rear of the house. Wall is in poor condition due to weathering. I want to install wall lights and then render. Advice required on best way to get power to the lights without visible boxes etc.
I'll get an electrician to install and certify, but can do the prep work myself. My current thinking is:
Dual wall ducting 500mm beneath flagged patio, with warning tape then through house wall below suspended wooden floor. 1mm SWA converted to 1mm T&E in a metal box screwed to the house wall beneath wooden floor, fed from a switched fused connection unit above floor level. SFCU either on the ground floor ring final or from a radial to an existing 20A MCB (for outside socket) in an RCD protected split load consumer unit. Or a separate RCBO. 2x 1mm SWA underground, then through PVC conduit chased into the wall up to PVC BESA boxes chased into the wall for the wall lights.
Is it ok to leave the SWA sheath un-terminated at the wall light?
Looking for best practice solutions for discussion with my electrician.
Thanks in advance.
