DC Disconnect and Over-Current Protection

For safety and to comply with regulations, battery over-current protection and disconnect devices are

required. Fuses and disconnects must be sized to protect the DC cable size used, and must be rated for
DC operation. Do not use devices rated only for AC service – they will not function properly.

Note that some installation requirements may not require a disconnect device, although over-current

protection is still required.
