3.1.5 Mounting Method

RA Series transfer switches are mounted to a wall. Follow the appropriate set of mounting instructions and

refer to the outline drawings in Appendix C for installation dimensions, specifications, and mounting hole

patterns. Enough room must be allowed to remove the door panel for inspection and servicing of the

switch, as per NEC and local codes.

3.1.5.1 Wall Mounting

1. Make sure that the wall where the transfer switch is to be mounted is suitable to hold firmly the

weight and size of the transfer switch, within a reasonable safety factor.

2. Check the location to be sure that no wires or plumbing, gas, or exhaust lines run behind the wall.

NOTICE

For Service Entrance models with integrated circuit breakers, the National Electric Code

stipulates that the installed height of the circuit breaker selector switch is not more than 6 ft

7 in. above the floor, grade, or platform.

3. Make sure that the anchorage fasteners used to bolt the switch to the wall are strong enough to

withstand the switch weight and its vibration during operation, within a reasonable safety factor.

4. Use four 1/4 inch bolts for wall mounting. Measure and mark the wall for drilling.

5. Install two mounting bolts in the wall for the top cabinet mounting keyholes.

6. With the shipping box standing so that the cabinet is lying down, carefully remove the top and the

foam from the box.
