Electrician Candice Hubbard sent me this guest post. It doesn’t really deal with EMFs but I thought it gave some useful insights into how a home electrical system works, so I decided to share it with you. Here’s her article:
A home electrical system includes the electrical service i.e. the electricity supplied to your house, lighting sockets and different hardwired electrical devices. The electrical power should be enough to handle the everyday life of the tenants, and is generally between 100 amps and 200 amps, even if 400 amps for an extremely big house is common. A commercial electrician sets up the service, and will often install cable TV and telephone wires and at times security systems.
The electrical cables run from the road to the meter box (the component where your power is read to establish your electric bill), after that through an external wall and straight into the electricity board, which encompasses switches also known as circuit breakers to manage the electricity in every room. Here, the amps are split up to supply different parts of the house with electricity. For instance, of the 200 amps accessible in a house, the circuit breaker for the sitting room might contain 20 amps; the circuit breaker for the bedroom might have 10 amps, and so forth.
- Circuit breakers that avert fires by disconnecting the electricity supply to a particular part if the cables short out.
- Ground fault circuit interrupters (GFCI) in high-humidity areas, for instance, bathrooms, kitchens, pool areas and garages protect dwellers from electric shock through disconnecting power to the circuit breaker.
- Smoke detectors in every bedroom and in common, rooms on every floor, like corridors, are linked to the system and interlinked to one another to notify dwellers of a fire. A good number of them have battery backup also.
Electrical systems as well are controlled by a local and international building code. For instance, electrical codes in several regions necessitate cabling to be in plastic, metal covering as an added fire deterrence measure. An electrical supervisor from static electrics should test the installation while the system is initially being wired and yet again when the house is completed to make sure all codes are adhered to and the power system is secure for you and your children.
If you have particular requirements, like a big visual/audio entertainment complex or a house, office, inquire from your designer whether they provide sophisticated cabling systems, and what they incorporate.
For instance, a builder might offer a sophisticated cabling system that can hold particular electronic functions, for instance, audio and video distribution. An access hub, or central supply panel, serves as the supply point for all inward bound data, telephone, satellite TV and cable lines. Information is passed over high quality, high-speed wiring, and ending in wall plates throughout the house. A sophisticated wiring system might as well incorporate dedicated fax, voice and workstation modem lines to assist you work from home.
Keep in mind; the position of communication wiring, electrical outlets and lighting cannot be altered. As well, identify what options are accessible and which ones work for you.
Not many people take the time to understand how their homes electrical system works, however Candice Hubbard a commercial electrician with static electrics has devoted her time to educate people how electrical systems should work.
