I agree. Although we have 240V (unspoilt) in the UK for normal domestic supply, so a single breaker per circuit is all that’s necessary, 440V 3 phase is also available upon request (and a lot of money) and although there would be a circuit breaker in each ‘leg’, the breakers would be ganged - one off = all off. Otherwise (as you say) if one breaker trips, it leaves the circuit/load at high potential and rather negates the effect of a single breaker disconnecting the supply.
Not only is this a danger to the operator, it can also lead to fires! I doubt that any insurance claim would be upheld if they found it had been wired in that fashion. 73, Alan - G4GNX South Coast UK Elecraft K4D / KPA500 / KAT500 / IC-9700 > On 20 Sep 2024, at 20:27, Rick Bates, nk7i <rick.n...@gmail.com> wrote: > > I would check on the code about the unganged breakers for a 240V circuit.
