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.
