    Only thing possibly is my system was running 3 and sometimes when it turned on my RCD tripped, have heard that they can spike, I do have a lot of standard lights as well so could have just been freak thing.

    Turning on lots of power supplies at the same time (particularly on the same circuit as other devices in your home) may result in trips. Best to try and stagger the PSUs power on/off cycles where possible. I have my show powered from 2 separate circuits of my house (left and right) and both sides use AC timers set a couple of mins apart so there is not a sudden spike.

    I have 8 Mean Well (200W - 320W SP series) power supplies that turn on at the same time via DMX relays and no issues. Cheaper power supplies (Mean Well or otherwise) often have a higher inrush, so may cause issues especially if sharing a breaker with other house circuits.

    I had 2 special circuits with RCD and timers installed so only lights are on these.

    That's why I was looking at mean wells as they don't peak like Chinese 1's.
