General Information 2.3.2— Utility Service Circuit Breaker (not supplied) This switch is listed for use with the following one inch breakers: • Siemens* • Murray* • Eaton • Square D *Including GFCI, AFCI and tandem breakers up to 50 amps. NOTE: For branch circuits over 50 amps, only listed Siemens or Murray circuit breakers shall be used. 2.4 — Transfer Switch Data Decal A data decal is permanently affixed to the transfer switch enclosure.
Section 3 Installation 3.1 — Introduction to Installation This equipment has been tested at the factory. Installing the switch includes the following procedures: • Mounting the enclosure. • Installing the circuit breakers. • Connecting power source and load leads. • Connecting the generator control wiring. • Connecting branch circuit wiring. 3.2 — Mounting Mounting dimensions for the transfer switch enclosure are in this manual. Enclosures are typically wallmounted.
Installation 1. Install a 2-pole, 100 Amp breaker in the main distribution panel. This will be the utility (normal) power source for transfer switch. 2. Install a conduit between the main distribution panel and transfer switch enclosures. 3. Run connections from 2-pole, 100 Amp breaker through conduit. 4. Connect utility (normal) power source cables to N1 and N2 terminals on the transfer switch mechanism. 5. Connect the generator (standby) source power cables to transfer switch terminals E1, E2.
Installation 2. Remove the ungrounded (hot) conductor from the circuit breaker and neutral conductor from the neutral terminal bar in the normal power panel board. NOTE: If the circuit to be protected is part of a multi-wire branch circuit, the entire multi-wire branch circuit has to be relocated to the transfer switch panel board. 3.

Section 4 Operation 4.1 — Functional Tests and Adjustments • Manual operation handle in the DOWN position LOAD terminals (T1, T2) are connected to EMERGENCY terminals (E1, E2). Following transfer switch installation and interconnection, inspect the entire installation carefully. A competent, qualified electrician should inspect it. The installation should comply strictly with all applicable codes, standards, and regulations.
Operation 4.2.3— Return to Utility Source Side 1. Manually actuate switch to return manual operating handle to the UP position. 2. Remove manual operating handle from movable contact carrier arm. Return handle to storage bracket. 4.3 — Voltage Checks Turn ON the UTILITY power supply to the transfer switch using the breaker in main distribution panel. DANGER Electrocution. High voltage is present at transfer switch and terminals. Contact with live terminals will result in death or serious injury.
Operation NOTE: See “Manual Operation”. Handle and operating lever of transfer switch should be in up position. 9. Turn on the utility power supply to transfer switch, using whatever means provided (such as a utility main line circuit breaker). The utility power source now powers the loads. 10. The system is now set for fully automatic operation. 4.5 — Checking Automatic Operation To check the system for proper automatic operation, proceed as follows: 1. Verify generator is in OFF mode. 2.
