The best fuses for this purpose are class T fuses, followed by class R time delay fuses. While main disconnects are required by the NEC, if yours is not fused , a large fuse needs be installed at the battery, typically on the positive line. Our choice is the class T fuse block. These single pole fuseblocks are perfect for fusing inverters or other large loads or inputs, such as chargers. The Class T fuse block is the ideal product to protect high amperage components, such as inverters, from damage by overloads and short circuits.
Installation is easy in either new or existing systems.
Simply cut cables and install.
