Choose Your Distribution Board
A distribution board (also known as panelboard, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
Normally, a main switch, and in recent boards, one or more residual-current devices(RCD) or residual current breakers with overcurrent protection (RCBO), are also incorporated.
Maintenance and Repair
Dirt, grime, bird droppings and insect residue can be removed by use of a mild degreasing solution mixture of one teaspoon per gallon of warm water. Gently scrub the housing exterior and rinse clean. Spiders and other insects can be controlled by use of a WATER-BASED insect spray.
WARNING: Turn off or disconnect the power supplying this equipment before beginning work. This might require you to contact your local utility to disconnect the power to an existing panel board or disconnect. The line side of the main breaker in a panel board is energized unless power is disconnected upstream.
Annual Main Lug/Main Circuit Breaker and Branch Circuit Breaker Maintenance
Open the main door and remove the gutter rails and dead front to expose the de-energized panel interior. The main lug/main circuit breaker and each circuit breaker lug should then be thoroughly examined for signs of excessive heating, loose and/or corroded connections, and any other sign of damage or wear. All loose or damaged connections need to be tightened or replaced.
It is critical that each termination be examined thoroughly for signs of corrosion. Most mechanical lugs are made of aluminum are highly prone to galvanic corrosion in the harsh marine environment. If any lug set screw cannot be fully tightened, that lug must be replaced before re-energizing.
Thoroughly examine the copper wire to aluminum lug connections for signs of corrosion. If any corrosion is found, simply remove the copper wire, clean the wire, coat with synthetic anti-corrosion grease and reinstall the wire.
