Amp Circuit
A low power circuit for lighting, most commonly used for task and table lamps
and now largely discontinued.
Bonding
All metal pipes in buildings must be earthed electrically by linking them all
together with wires, which are then connected to earth. This is done to prevent
severe electrical shock to persons should the pipes become live through a fault.
Circuit Breaker
A switch that replaces a fuse to protect from electrical overload. If the
circuit breaker is activated, pushing in the button can reset it but the reason
for activation should always be investigated, especially if there is a repeat.
Consumer Unit
The panel beside the meter on the consumer side of the meter, which contains
fuses or circuit breakers.
Earth Leakage
This has the same function as RCD in cutting the power if minute currents are
detected.
Flex
Cable where the electrical conductor core is made up of many fine strands
instead of the single wire as in twin and earth.
Fuse
The thin wire in a carrier which protects an electrical circuit. Fuses occur as
a cartridge or loose wire.
Megger
A testing meter used to check the resistance of electrical circuits,
particularly earths, through a small power source which sends several thousand
volts at very low power through the circuit.
Rcd
Residual current device or breaker on the board beside the main fuses or circuit
breakers. This can also be a local device switch as a socket or plug-in. The
device monitors the earth and if it finds any current which has crossed from the
live side, it switches off the power in a split second, thereby protecting
persons from electrical shock.
Ring
The power circuit to sockets is found in the form of a wire looped from socket
to socket and back to the circuit breaker to save on wire. This is known as a
ring.
Radial
Similar to a ring but fed from one end only.
Twin and Earth
Standard power cable supplying sockets.
Two Way
The arrangement of two switches, which are linked so that either can switch a
light on or off.
