Notes:
1. All wire sizes assume separate conduit for each set of
parallel conductors.
2. All wire sizes based on NEC Table 310-16 for THW wire (copper).
Canadian electrical code wire ampacities may vary.
3. All wire sizes assume no voltage drop for short power leads.
*To provide that disconnects and power blocks mate with power wiring.
