Existing Equipment, Location Issues not in line with BS 7671 section 729

Simon Port

A client has a voltage optimization unit (tapping transformer) installed in a small room with a single entrance. The room is adjacent to the main low-voltage distribution board.

The current installation doesn't meet the required 700mm clearance in front of the unit, preventing the door from opening fully. This poses a safety concern as there's no clearance when the door is open.

We've been asked to replace the unit, but the location seems non-compliant.

Is there a way to proceed with the replacement without relocating the unit? Could the client sign a waiver acknowledging the non-compliance and potentially restrict access to the room when the equipment is live?

Please advise on the best course of action to ensure safety and compliance

    Just thinking out loud, what sort of size and construction is the VO unit? Is it not adequately enclosed so that ordinary persons might be at risk if they could access it? I tend to think of section 729 as covering big industrial stuff - e.g. where massive circuit breakers have to be racked out for routine maintenance - so I wonder if it's applicable in this case.
