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.
3. 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.
