3.9.1 tables for wire and breaker Sizing - AC output Side
Table 3.3 provides details of wire and breaker sizing for the AC output side.
AC wiring and breaker sizes on the AC output side are required to be determined by the
rated Load Current when operating in Inverter Mode (Column 1).

1) Column 2 indicates the rated AC Output Current in Inverter Mode
2) Column 3 indicates the Amp rating of EXTErNAL breaker that is required to be
installed in the Load Consumer Unit / 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 the rated output current at Column 2
b) Type of breaker: Standard Moulded Case Circuit breaker (MCCb) for 230VAC,
50Hz Consumer Unit / Load Center / breaker Panel
3) Column 4 indicates conductor size based on the following guidelines:
a. british Standard bS 7671 : 2008 - requirements for Electrical Installations:
(i) Table 4D2A for multi-core, 70°C copper conduct cable
(ii) Ambient temperature of 30°C
(iii) reference method "b"- enclosed in coduit on a wall or in trunking, etc.
(iv) 1 two-core cable with Protective Earth (PE) conductor
(v) Conductor temperature rating has been taken as 70°C to meet 70°C
maximum temperature of MCCb terminals as per bS EN-60947-2
b. Current carrying capacity = the MCCb rating at Column 3
