Doing a run of gigs with a function band for the last few days, and two days ago I ran into a nice 32amp 3 phase ceeform outlet, on the end of an appropriately sized 2 metre cable coming from a switched wallbox... installed behind 10 or so stacked folding rolling hotel banquet tables, in the storage room behind the hotel's stage, with no way of getting the cable out of the store-room into the ballroom without leaving the door open. The hotel insisted on leaving the fluoroescent lights in the storeroom on.
So even though the installation was electrically fine, it was not really thought through...
Last night a different hotel gave us 4 metalclad 13 amp sockets (UK type) behind the stage. First song in and we tripped the breaker. Some investigation ensued with the hotel staff and we found that we were on the same power feed as the 4 large 3phase space heaters that they were using to heat the ballroom; the total breaker capacity was 25amps. They then claimed that the fairy lights behind the stage were most likely the problem, and proceeded to unplug them as they were on the same feed that we were using.
Problems stoped after they unplugged the space heaters...
Hopefully tonight will be better, but I wouldn't bet on it....
