Hi there
Just completed the electrics for a heat pump install in a large office block, just trying to complete th paper work, but have a problem.
When checking the Main Isolator type it is a Merlin Gerin Selpact 400A Air circuit breaker, it has no bs number.
Anyone got an idea what BS number to put down for these ?
