250 mA fuses and disconnect switch LVCS with insulation rated for the installation voltage and the installation/ measurement category NOTE: LVCS refers to both LVCT and Rogowski coil. VT primary fuses and disconnect switch indicates wiring for a balanced system + indicates white wire - indicates black wire Clearly label the device’s disconnect circuit mechanism and install it within easy reach of the operator. Fuses / circuit breakers must be rated for the installation voltage and sized for the available fault current. Fuse for neutral is required if the source neutral is not grounded.
