Section 4 - Samlexpower Evolution EVO-2212 Owner's Manual

SECTIOn 3 |
4) Column 5 indicates the Programmed AC Input Current Limit. The value of this cur-
rent limit is called "GrID MAX CurrENT" / "GEN MAX CurrENT" for programming
purposes and is programmable using the optional remote Control Model EVO-rC
(See Appendix A, Section 4.5 for Input Settings -"GrID MAX CurrENT" / "GEN
MAX CurrENT"). Appropriate value can be programmed to match the available
capacity of the Grid input AC branch Circuit or the rated capacity of the Generator.
Default value for all the 4 models is 30A and is based on convenience of power-
ing these units from the standard 30A main power inlet plug (wiring 30A cord) on
motorhomes / rVs.
5) Column 6 indicates NEC Ampacity based on which the wiring conductor size
(Column 7) is determined. This NEC Ampacity is not less than 125% of the
Programmed AC Input Current Limit (Column 5) - refer to NEC-2014 (National
Electrical Code) - Section 210.19(A)(1)(a) regarding minimum Ampacity and size of
branch Circuit Conductors.
6) Column 7 indicates the wiring conductor size that has been determined based on
NEC-2014 (National Electrical Code) - Ampacity Table 310.15(b)(16) for raceway.
This conductor size is based on (i) NEC Ampacity (Column 6) (ii) conductor
temperature of 75°C / 167°f and (iii) ambient temperature of 30°C / 86°f.
7) Column 8 indicates the Amp rating of EXTErNAL breaker that is required to be
installed in the Load Center / breaker Panel feeding the unit. The Amp rating of
this breaker is based on the following considerations:
a. Not less than the NEC Ampacity (Column 6) - refer to NEC-2014 (National
Electrical Code) - Section 210.20(A) regarding overcurrent protection of
branch Circuit Conductors. however, the Amp rating of the fuse has to be
≤ the Ampacity of wire size at Column 7 based on Table 310.15(b)(16) for
raceway (conductor temperature of 75°C / 167°f and ambient temperature of
30°C / 86°f).
b. Closest Standard Ampere rating of breaker has been used - refer to NEC-2014
(National Electrical Code) - Section 240.6(A) regarding overcurrent protection
c. Where Standard breaker rating does not match the required NEC Ampacity
(Column 6), the next higher Standard rating of the breaker has been used -
refer to NEC-2014 (National Electrical Code) - Section 240.4(b) regarding over
current devices
d. Type of breaker: Standard circuit breaker for 120VAC Load Center /breaker Panel

AC breakers for the AC output circuits have NOT been provided internally. These have to be
provided externally by the installer / user based on guidelines given below. Please note that
guidelines given below on wire sizing and over-current protection will be superseded by the
applicable National / Local Electrical Codes.
