This Power Strip contains 6 outlets, each outlet can be fused up to the value of the Main fuse. The Main Fuse is 40 AMPS. The Main Power to this unit is via a dedicated 8 foot piece of 8AWG wire. There is a Switch on one end that turns on or off all outlets. Fuses are of the ATC/ATO style and available at most Automitive stores. Our Power Strip has an LED Bar-Graph that monitors the voltage on the Strip. If the input voltage to our unit exceeds 15 Volts, +/- 0.7 Volts, the voltage to the outputs will be shut off. Also if the voltage falls to 10.5 Volts +/- 5% the outputs will turn off. If the input voltage returns to normal, normal operation will automatically be restored. Blown Fuse indicators are provided next to all fuses. An LED will glow indicating a blown fuse. Comes with a 10 pair bag of connectors, Owners Instructions and a Warranty Resistration Card.
