(2) When using the 40-amp distribution system, determine the number and
location of 100-amp and/or 200-amp feeder systems, if any.
(It is more efficient to
locate the power consuming equipment as close to the power source as possible, thereby
minimizing the need for feeder systems).
Refer to Table 1-4 for pairing of the 40-amp
distribution system to the appropriate sized generator.
