Played a gig on the weekend and had some serious power issues, we were supplied with a 3-phase to single-phase circuit breaker box, most likely with RCD protection. This box takes 415V 3-phase and gets a line voltage of 240V by taking power from one phase and neutral. There were 3 separate "circuits" between each of the 3-phases and neutral.
I took one of those circuits to power the front of house/keys (logistically easier), one for the power amps that feed the foldback, and one for the backline.
A few minutes after powering up, one of the FOH speakers died in spectacular fashion, loud pop and smoke. Cue me running to trip the main 3-phase breaker. It also blew the keyboard (Nord Stage II...), and also blew a fuse in one of the guitar amps, and a fuse on my MIDI foot controller (separate circuit to the FOH/keys).
I'm thinking there was a problem between a couple of the phases, maybe insulation breakdown and we got a tad (OK lots) more than the 240V we were supposed to have. Worth noting we did a separate gig a few days ago with a similar setup with the 3-phase to single, and no issues.
Anyway I think I need some kind of power protection, for serious over-voltage/current events like this, something that will either condition the power of just trip so I can reset it. I use a Kemper with a power amp, plus a wireless system and the foot controller. Would be also nice be able to use it at home on my valve amps.
It needs to be portable (I'll put it in a rack with the Kemper and wireless) and robust, and 240V.
Any suggestions??? Thank
