DC Connection Specifications
The voltage rating of the DC conductors must meet or exceed 1000VDC. When connecting to the fuse holders, use copper
PV conductors. Fuse holders can accommodate conductor sizes ranging from 14 to 8 AWG (2.5 to 8.4 mm
2
). All electrical
conductors must meet the requirements of the NEC and local electrical codes.
