A DJ I respected plugged every piece of equipment into one circuit. He was going over-the-top, wanting to give the Bride and Groom the best experience possible. Then it happened. During the height of dancing, the lights and music turned off. He tripped the breaker. Too much was plugged-in.
This happened over and over again until I suggested he split the load between two circuits. I helped him do it and everything was fine from that point out.
This was early-on in my DJ career; I was also going to school for Electrical Engineering Technology. Ever since then, I always do my best to ensure a breaker doesn’t need reset at a wedding. No music is the quickest way to kill a dance floor :)
