General input power requirements

The switches, fuses, and cords that you supply must comply with all applicable national and local electrical codes and requirements, and be installed by a licensed electrician.

As an installer or user, you are responsible for supplying all of the switches, time-delay fuses, and power cords necessary for cutting system installation and operation at the installation site.

General input power requirements are in the following table. For specific requirements for switches, fuses, and cords, refer to Line-disconnect switch requirements, Circuit breaker or fuse requirements, and Main power cord requirements.
