Wire Gauge VS. Recommended Max Fuse Size*
0 awg = 325 amps
1 awg = 250 amps
2 awg = 200 amps
4 awg = 150 amps
6 awg = 125amps
8 awg = 100 amps
10 awg = 60 amps
12 awg = 40 amps
14 awg = 25 amps
16 awg = 15 amps
*This is a general guide. Always go with the
equipment manufacturer's recommendation.

All wire gauges in AWG (American Wire Gauge)

To Compute system current draw requirements
you must first ascertain the approximate current draw (in amperes) of the load (your amplifier or amplifiers). Calculate the total power of each amp by multiplying the number of channels by the number of RMS watts per channel). If you have multiple amps, add up the total power figures to arrive at a grand total. Second, double your grand total power figure. And, last, divide by 13.8. The result is your system's approximate max current draw in amperes. Typical examples are below:

Current Draw by Power

(RMS total watts) Power.....................Current (max Amperes)
100---------------- 14.5
200----------------- 29
400------------------ 58
600----------------- 87
800---------------- 116
1000--------------- 145
1200--------------- 174
1400--------------- 203

Current in this case, is the maximum amount of pre-clipping amperes drawn. With all amplifiers, in the quiet state, less than an ampere may be consumed. Power drawn is proportional to signal amplitude on an exponential curve. System wiring should always be configured for the highest rated consumption usage.
