Down the left facet of the phase busbars are two two-pole RCBOs and two single-pole breakers, one unused. The two-pole RCBOs in the picture usually are not related across two phases, however have supply-side neutral connections exiting behind the part busbars.

The primary breaker is used to show energy to all of the branch circuits ON or OFF on the same time. The main service panel is just like the switchboard for all of the electrical energy within the house. It receives the incoming power from the utility company and distributes it to every of the circuits that provide the various lights, shops, home equipment, and different gadgets throughout the home. Everything but the incoming utility energy could be shut off and turned on on the primary service panel. With that protecting cover eliminated, shutting off the panel’s primary circuit breaker switch will not essentially maintain you secure.
