Updating old home wiring

Some “smart meters,” used on homes which generate renewable energy from wind or solar, will count electricity flowing both into and out of a home.This allows homeowners generating renewable energy to sell excess renewable electricity back to the electric utility.” From the smaller circuit breakers, bundles of wires run through walls, ceilings, and floors to each room and hard-wired appliance.Here are a few things you may want to consider in your home’s electrical system design and communicate to your architect or electrical engineer who is helping to plan your system: · A well-thought out lighting design is vital.Lighting affects not only the aesthetics and ambiance in a home, but also the safety and security of its occupants and the home’s overall energy efficiency.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 main line typically comes off a pole (but can also be buried underground) to the house where it connects to the meter.Ashenfelter says, “In most areas building permits are required and can be obtained from your local building department.” Systems should always be installed by trained professionals, adhering to the most current codes.

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 (k Wh).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 total increase in the number of k Wh from one month to the next is the number used by the electric utility for your bill.
