Consumer Unit

The Consumer Unit.
The Consumer Unit (Fuse box) is the
engine of your electrical installation.
It protects all the circuits from
overloading the wiring and causing
major problems or even fire.
Modern Consumer Units.
Modern, more up to date fuse boxes
incorporate RCD’s and MCB’s which trip when
a circuit overloads. Older types of consumer units use
a piece of fuse wire between two
blades that needs replacing every
time you have a short circuit.
