NOTES FOR TABLE 3.3 - AC OUTPUT WIRING AND BREAKERS
1) Column 2 indicates the Rated AC Output Current in Inverter Mode
2) Column 3 indicates NEC Ampacity based on which the output-wiring conductor
is sized. This NEC Ampacity is not less than 125% of the Rated Output Current in
Inverter Mode (Column 2). - Refer to NEC-2014 (National Electrical Code) - Section
215.2(A)(1)(a) regarding Feeder Circuit Conductors. PLEASE NOTE that when the
unit is operating in Inverter Mode, it is considered to be an AC source that is feed-
ing power to the Load Center / Breaker Panel on the load side. Hence, the AC out-
put circuit of the unit is considered to be a Feeder Circuit for purposes of NEC-2014.
3) Column 4 indicates conductor size for the output side wiring. The size is based on
NEC-2014 (National Electrical Code) - Ampacity Table 310.15(B)(16) for Raceway.
Conductor size is based on (i) NEC Ampacity (Column 3), (ii) conductor temperature
of 75°C and (iii) ambient temperature of 30°C / 86°F.
4) Column 5 indicates the Amp rating of EXTERNAL breaker that is required to be in-
stalled in the Load Center / Breaker Panel that is being fed from the AC output from
this unit. Amp rating of the breaker is based on the following considerations:
a) Not less than NEC Ampacity (Column 3) - Refer to NEC-2014 (National Electri-
cal Code) - Section 215.3 regarding over-current protection of Feeder Circuit
Conductors
b) Closest Standard Ampere Rating of Breaker has been used - Refer to NEC-2014
(National Electrical Code) - Section 240.6(A) regarding Standard Ampere Ratings
c) Where Standard Breaker Rating does not match the required NEC Ampacity at
Column 3, the next higher Standard Ampere Rating of the breaker has been used
- Refer to NEC-2014 (National Electrical Code) - Section 240.4(B) regarding over
current devices rated 800 Amps or less
d) Type of breaker: Standard circuit breaker for 120VAC Load Center /Breaker Panel
