Our blowers which are used to inflate the bounce units, each require a 20 amp dedicated circuit. It seems confusing when you see multiple plug sockets and think you could just use them, but plugging in more than 1 blower on a circuit will make the power breaker trip. Sometimes we need to run power from different areas of the house or building to ensure they are on different breakers (circuits). We also strive to have circuits close enough (within 50'-100' max) because we chance heating cords and or damaging our equipment. This is why we offer to help provide the party power.
