How do you calculate what size fuse you need?
B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125% = 100A.
What gauge wire should I use for a 2000 watt amp?
Up to 500 watts RMS = 8 gauge. 500 – 1000 watts RMS = 4 gauge. 1000 – 1500 watts RMS = 2 gauge. 1500 -2000 wats RMS = 0 gauge.
