Your Home Wiring System
Overview:
If
you have only limited knowledge of electricity or
are unfamiliar with the home wiring code, the
standards by which houses are wired, you probably
should not be doing your own wiring. Your home
wiring system is designed to function properly and
prevent fire or injury.
Your home wiring system needs to be in the best
possible condition so that all the appliances and
light fixtures in your home are supplied with the
adequate amounts of power without compromising on
safety.
In
most homes the electrical service is divided into
circuits or branch circuits where each circuit
supplies power to a certain section of the house to
power appliance and lights. Good home wiring
ensures that each circuit and branch circuit
carries a proper current load that is rated for the
appliances and lights that are on the circuit,
otherwise there will be an overload on the circuit
and you’ll be spending a lot of time resetting
circuit breakers or replacing fuses to deal with
the overload.
Many major appliances such as electric stoves,
refrigerators, dryers, and boilers take so much
power that they require their own dedicated
circuits. For instance, an electric stove or dryer
requires its own 240-volt circuit, while other
appliances such as refrigerators require 120-volt
circuits. In most cases a single circuit provides
electric power to appliances that require a lot of
power. For small kitchen appliances and lights and
outlets using a varying amount of power and are
wired on circuits for multiple outlets, usually not
to exceed 15 or 20 amps.
A
typical home electrical circuit plan makes use of
branch circuits that provide power to areas that
serve a specific purpose such as a bathroom or a
garage. In new homes the electrical wiring circuits
are well thought out and wired to the standard
national code but the danger in house wiring
is when a home is renovated by inexperienced
do-it-yourself electricians that are not familiar
with code requirements and wire circuits in an
unorganized manner. A properly wired home provides
sufficient power in an organized way to all
circuits in such a way that the circuits are not
overloaded. Even in remodeling the electrical
circuits should be organized by each room with the
proper wiring and rated circuit breaker protection.
For example if the circuit requires 12 amps of
power you use #14wire, but if the circuit requires
20 amps of power you must use #12 wire. For high
current circuits such as for dryers and electric
stove # 10 or # 8 wire is required depending on the
rating the distance the appliance is from the
electrical panel.
If
you are experiencing problems with overloading
circuits and want to check how much current a
particular circuit is wired for just look at the
circuit breaker or fuse to determine how many amps
the circuit is rated for. If the appliances on the
same circuit exceed the amperage that circuit is
rated for, move some items off that circuit to
another circuit. Another solution is to add another
circuit to your electrical system.
Wiring your home can be an
involved process, especially if you have no prior
electrical experience. Although household wiring is
not difficult it does require knowledge and
experience. It can be a dangerous challenge for an
amateur without experience. If you are planning a
renovation of your home without professional help
you may want to consider hiring an electrician to
deal with your home wiring system.
