Shorting block

VT primary fuses and disconnect switch

• indicates wiring for a balanced system

Clearly label the device’s disconnect circuit mechanism and install it within easy reach of the operator.

Fuses / circuit breakers must be:

• Installed in accordance with all local and national electrical codes and standards.

• Rated for the installation voltage, available fault current, and sized for connected loads.

Fuse for neutral is required if the source neutral is not grounded.
