Residential Electrical Term Fuse is a protective electrical
device. A fuse is rated for a maximum amount of current flow
which is measured in amps. Electrical current is measured in
amperes also called amps. When the current flow exceeds the
amperage rating on the fuse, the fuse link in the fuse will open
and stop the flow of current. Years ago everything, both AC and
DC current, were protected with fuses. Today most have been
replaced with electrical breakers
Residential Electrical Term Romex is a particular type of
electrical wiring used mainly in new home construction. Romex
consists of a certain size wires wrapped in a plastic sheath. A
