So I recently upgraded my printer to heat the bed with 110v AC. I've been a bit paranoid about this and have added safety checks to the printer, however I am worried what effects the printer has on the house electrical system as a whole. I have two solid state relays driving a total of 1050W worth of power and I noticed toggles quite a bit once it reaches the target temp. The relays are cool to the touch, but I am worried if they pose any hazard to the outlets them selves.
