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.
