201192 - 30 AMP MANUAL TRANSFER SWITCH
Branch Circuit Wiring (USA Installation)
 WARNING
Rating of a transfer switch circuit breaker is not to exceed the
rating of the corresponding branch circuit breaker in the main
service panel.
1. From the main service panel, select a branch circuit to be
powered by the generator during a power outage. When no
power outage, selected circuits will be powered by utility.
NOTE: Multi-wire branch circuits must be connected to circuit
breakers adjacent to each other. If the selected circuit to be
powered by the generator is part of a multi-wire branch circuit,
the entire multi-wire branch circuit must be relocated to the MTS.
(Ref. NEC 210.4). Branch circuit wiring can be removed from the
main service panel and installed in the MTS or spliced onto a new
branch circuit originating from the MTS.
2. Turn off selected circuit breaker in main service panel.
3. Remove HOT wire from selected circuit breaker.
4. Remove NEUTRAL wire from bus bar of selected circuit.
5. From the MTS, select a branch circuit that is LESS THAN
or EQUAL TO the circuit breaker ampacity of the selected
circuit breaker in the main service panel. Locate that circuit
breaker’s colored wire from the pre-wired bundle and connect
to the HOT wire removed from selected circuit breaker in
main service panel with approved wire connector.
6. Locate that circuit’s corresponding NEUTRAL wire from the
pre-wired bundle and connect to the NEUTRAL wire removed
from the selected circuit in main service panel with approved
wire connector.

Branch Circuit Wiring (Canada Installation)
The Canadian Electric Code prohibits the use of the main service
panel as a junction box. The selected branch circuits are to be
connected to the MTS circuit wiring inside a proper junction box or
directly connected to the circuit breakers inside the MTS.
Junction Box Connection Method
1. Mount proper junction box near main distribution panel so
selected branch circuit wires can be routed and connected
inside the junction box.
NOTE: If required, size all conductors, raceways, conduits, and
junction boxes to comply with applicable Canadian Electric Code
(CEC) installation requirements for wire installation.
2. From the main service panel, select a branch circuit to be
powered by the generator during a power outage. Note: When
no power outage, selected circuits will be powered by utility.
NOTE: If the selected circuit to be powered by the generator is part
of a multi-wire branch circuit, the entire multi-wire branch circuit
must be relocated to the MTS.
3. Turn off selected circuit breaker in main service panel.
4. Remove HOT, NEUTRAL, and GROUND wire of the selected
circuit.
5. Pull cable out from main service panel and re-route to the
junction box.
