Fuseboards
In
todays world, we use more and more electrical appliances so often,
that fuseboards are overloaded to current safety standards, and
become unprotected and dangerous.

from £300. FREE no obligation quotes.
A
guide to your fuse box
A consumer unit or fuse-box is a particular
type of distribution board comprising a co-ordinated assembly for
the control and distribution of electrical energy, principally
in domestic premises.
A consumer unit incorporates a manual
means of isolation on the incoming circuit(s): a main switch and
an assembly of one or more fuses, circuit-breakers or residual
current devices (RCDs).
Fuses: Rewireable
fuses have a piece of special fuse wire running between two screws.
The fuse wire generates heat when a fault current flows through
it and it melts when the heat exceeds the acceptable level. The
melted fuse breaks the circuit and stops the electricity supply.
Circuit Breakers: Circuit
breakers, fuses and RCD’s are protective devices that will
interrupt the flow of electrical current, if the circuit concerned
develops a fault.
Instead of a
modern unit like the one shown with circuit breakers and RCD’s,
some older houses have fuse-boxes with re-wireable fuses. RCDs: A residual
current device is a mechanical switching device or association
of devices intended to cause the opening of the contacts when the
residual current attains a given value under specific conditions,
such as under earth fault conditions. |
