All About House Electrical Wiring System – A Small Guide
The house electrical wiring systems is way more complex than you see it to be. When constructing your own home, spend fairly good time in mapping the circuits, power points, panels for your ease and specifically at the spaces where they are out of the children’s reach. In house wiring, a circuit usually indicates a group of lights or receptacles connected along such a path. Each circuit can be traced from its beginning in the service panel or subpanel through various receptacles, fixtures, and/or appliances and back. Just one of the most important thing that runs along and connects every appliance to every plug, they run across like veins mapping your home. It then becomes very imperative to install high quality wires like PRIME CABLES, which are durable, heat resistant, lead free and flame retardant. Here is a small guide for you to plan and set-up the correct wiring system for your home.
Consider these points before going ahead with your electrical wiring system:
An electrical service large enough to support the electrical needs of the home (with room for future additions).
An electrical box that is properly wired, sufficient for the home’s power needs, and has not been recalled. (There have been many electrical panel recalls, both old and current.)
Wiring that is in good working order (not aluminum, knob-and-tube, exposed, crimped, cracked, or damaged).
Switches and outlets in good working order and the right type for the job/location in the home. (Plugs are supported in outlets; outlet boxes are not loose.)
GFCIs are in-use in moisture-prone areas, including kitchen, laundry, bath, basement, garage, crawlspaces, and outdoors.
Common homeowner electrical mistakes (wrong wire size; loose connections; missing junction boxes; exposed wires; wrong amperage circuit breaker; overloaded outlets/circuit…).
What are the major components of an electric system: The electrical system consists of the line from the pole, a meter where electrical usage is tallied, a main circuit breaker panel (sometimes called “load centers” and, in older homes, fuse panels), separate wiring circuits to all the rooms in the home, outlets, light fixture boxes, and various hard-wired appliances.
The Meter: The main line typically comes off a pole (but can also be buried underground) to the house where it connects to the meter. Meters are typically installed on the exterior of the home, where they can be read by utility company meter-readers. Most meters are mechanical, with a spinning wheel and mechanical display of numbers. Some newer meters are digital, showing a display on an LCD screen. The meter tallies the amount of electricity used in a home in units of kilowatt hours (kWh). The total increase in the number of kWh from one month to the next is the number used by the electric utility for your bill.
The Circuits: Each bundle of wire has at least three wires within – two with plastic insulation and one bare. The black and/or red insulated wires are the “hot” wires coming directly off of the circuit breakers. The white insulated or “neutral” wire carries the current back to the electrical source at the panel. The bare copper wire is the ground wire, which is the safety part of the circuit. The two wires insulated wires are attached to outlets or switches so that when nothing is plugged in or a switch is in the off position, the wires do not meet. When you plug something into an outlet or turn a switch on, you complete the circuit, allowing electricity to flow through a light or appliance to activate it.
GFCIs: A GFCI senses the moment when a person begins to receive a shock, and shuts off the electricity at the outlet or breaker within milliseconds, avoiding the shock and potential electrocution. GFCIs are typically installed in locations where water may be present, like bathrooms, kitchens, unfinished basements, garages, and even outdoors. The most common type of GFCI is the outlet, but GFCI breakers can also be used in the main breaker panel to give all outlets in a given circuit GFCI protection.
GFCIs look like typical electrical outlets, but also include a test and a reset button. In the event that a GFCI is tripped, pressing the reset button will restore power (assuming the original problem is fixed). Since GFCIs include electronic sensors, and are subject to possible failure over time, homeowners should test them once a month to ensure that they are still working. Press the test button, which will trip the GFCI, then press the reset button to restore power. If pressing the test button doesn’t trip the GFCI, or pressing the reset button doesn’t restore power, the GFCI should be replaced.
All these points should enough for you to consider while changing or re-installing the wiring system at your home. Prime cabs ensure a safe wiring system for all your wiring needs that would need minimal change for years to come.
