NOTE: Refer to NEC (or applicable national and local electric code) for output wire size based on
output breaker size and Article 310 Section 8A as mentioned in Step E below.
INPUT WIRE SIZE, GROUNDING AND OUTPUT WIRING
A. Conduit should be used for both input and output wiring.
B. Minimum ground wire size is based on 1990 Nation Electric Code Table 250.
C. Input wire size is based on 1990 NEC Table 310-16 specifying not more than 3 conductors
in a raceway based on ambient of 30° Celsius, and wire rated at 75° Celsius.
D. Output neutral to ground is already bonded during manufacturing of Power Conditioner.
E. Output requires 4 (5 including ground wire) conductors in a raceway assuming neutral as
a current carrying conductor. This requires conductors to be derated by using a multiplier
of .8, reference 1990 NEC Article 310 Section 8A.
Example:
1. Assume #10 wire max current = 25 Amps.
2. Multiply 25 x .8 = 20
3. 20 Amps is max current for #10 wire in a raceway with 4 conductors.
NOTE: Installation is subject to local codes - verify with a local electrical inspector.
