I do some side handy work. I went to a clients house today to assemble a computer desk in their master bedroom. I assembled the desk and then the client asked that I move the printer from bedroom #3 to master bedroom. The computer was powered on in bedroom #3...and appeared normal. When I moved it to master bedroom and plugged it in, during the warm up phase, it tripped the 20amp breaker...strange. I moved the printer to various outlets in master bedroom and all are on the same circuit. Can't figure out why...so client suggests moving it back to bedroom #3. I plug it in bedroom #3 and low and behold it trips the circuit breaker upon start up. Thank Goodness I had not done any electrical work for them up to this point! So, I bring the printer into kitchen, plug in and works fine. Bring back to bedroom #3..trips the breaker. Its been in bedroom #3 for over a year working fine. I move the thing and its possessed? It s just a brother wireless printer, weights like 15lbs. Any ideas?
