Relay question

  1. Jul 13, 2015 #1
    I am using an 1/8 HP motor with an SCR type dc drive and 1/4hp AC single phase control relays. I keep having a problem with welded relay contacts. Should I go to 1H/P relays? I dont know why I would have to being the HP of the motor is lower that the relay?

    Motors draw a lot more current on start-up.
