A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) 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.
Circuit breakers with higher ratings can have adjustable trip settings, allowing fewer standardized products to be used, adjusted to the applicable precise ratings when installed. For example, a circuit breaker with a 400 ampere frame size might have its over-current detection threshold set only 300 amperes where that rating is appropriate.
The most common form is the 16 series, rated at 400 amperes with 105 °C terminations. Also in common use is the 15 series (mini-cam), rated at 150 amperes. A larger version is made denoted as the 17 series with ratings up to 760 A. A ball nose version and a longer nose standard version exist—the latter is the most common.
This AFCI (the circuit breaker with the yellow label) is an older generation AFCI circuit breaker. The current (as of 2013) devices are referred to as "combination type." An arc-fault circuit interrupter ( AFCI ) or arc-fault detection device ( AFDD ) [ 1 ] is a circuit breaker that breaks the circuit when it detects the electric arcs that are ...
These connectors are single pole so five are required to accommodate all three phases, neutral and ground. Powerlocks have a rating of 400 A or 660 A at 1 kV. Cam-Lok E1016 Series are rated at 600 V 400 A. Powerlocks are identified with the European harmonized colour code, they are also annotated as follows: Brown, L1 Black, L2
Panel Drain (female) connectors, for feeding power in to a portable distribution cabinet Powerlock is a range of single-pole electrical connectors used for temporary high-current, low-voltage (up to 1000 V AC) applications, [ 2 ] similar to but considered safer than camlock connectors.
