Hi,
I want to add a change over switch so that a portable backup petrol generator can be used when grid power goes down. As it has in Victoria. On referring to AS/NZS 3010:2017 to connect a portable generator. Figure 4.3 on page 57 shows a 1 pole Circuit Breaker in the active wire between the Change over switch and the 3 pin Appliance-inlet. With the neutral wire going from the change over switch direct to the 3 pin Appliance-inlet with no Circuit Breaker inserted in it. That is the Circuit Breaker is only in the active wire only and not in the neutral wire.
Yet section 4.3.2.3 Current limiting of incoming supply on page 53. Indicates:
Each incoming supply to the installation from the generator set shell be protected by a separate overcurrent protection device located within the electrical installation and, operating in all live (active and neutral) conductors. That is to use a 2 pole Circuit Breaker that is in both the active wire and neutral wire going to the 3 pin Appliance-inlet,
Which is correct. Is Figure 4.3 that shows a 1 pole Circuit Breaker in the active wire only. Or section 4.3.2.3 that indicates that a 2 pole Circuit Breaker in both the active wire and neutral wires that goes to the 3 pin Appliance inlet.
I think the correct answer is to use a 2 pole circuit breaker in the active and neutral going to the 3 pin Appliance-inlet. But am I correct?
