  • Page 8: Section 2 - General Information

    Electrical Requirements It is extremely important that any Precor treadmill be connected to and operated on a dedicated 20 amp AC branch circuit. A Dedicated Branch Circuit is defined as a circuit fed by a single circuit breaker feeding a single load, with a single non-shared neutral providing a return line.
