2. The circuit breaker correctly feeds a single A.C. outlet but the neutral is common

between several A.C. outlets.

The common neutral lead must be removed from treadmills A.C. outlet and a new neutral

lead from the treadmills A.C. outlet to the A.C. neutral distribution bar must be added.

3. Both the hot and neutral leads feed several A.C. outlets.

Both the common neutral and hot leads must be removed from treadmills A.C. outlet and a

new neutral lead and hot lead from the treadmills A.C. outlet to the A.C. neutral distribution

bar and circuit breaker must be added.

240 Vac Systems

240 Vac distribution systems utilize a double pole circuit breaker (two hot leads) The A.C. safety

ground (green wire) is connected to a ground bar in the distribution system.

The most common problems found are (1) the circuit is fed by a circuit breaker of less than 20

amp capacity and (2) both the hot leads feed several A.C. outlets. The appropriate correction

action or actions (see below) must be followed if any of the above conditions exist. Corrective

actions should only be undertaken by a licensed electrician.

1. The circuit breaker feeding the treadmill is not a 20 amp circuit breaker.

If the circuit breaker is greater than 20 amps, the circuit breaker should be replaced with a

20 amp circuit breaker. If the circuit breaker is less than 20 amps the circuit breaker must be

replaced with a 20 amp circuit breaker and the wiring from the A.C. distribution must be

capable of safely handing 20 amps. If the A.C. wiring is under sized, it must be replaced

with wire capable of safely handling 20 amps. Please, refer to local electrical codes when

determining the appropriate wire size for a 20 amp circuit.

2. Both the hot leads feed several A.C. outlets.

Both hot leads must be removed from treadmills A.C. outlet and two new hot leads from the

treadmills A.C. outlet to the circuit breaker must be added.

A licensed electrician may use the followings hints to determine if an A.C. service is dedicated.

1. If, on a 120 Vac system, the A.C. distribution panel contains more circuit breakers than

neutral leads, the system has shared neutral leads and is not dedicated.

2. If an A.C. outlet (120 or 240 Vac) has multiple hot and/or neutral leads, it is not a dedicated.

If either of the above conditions exist, the system is not dedicated. However, absence of the

above conditions does not necessarily mean that the system is dedicated. If any doubt exists

about A.C. systems dedication, point to point tracing of the A.C. wiring may be the only way to

prove system dedication.
