Ifyour electrical panel needs replacing, you might need to add a new panel to the total cost to rewire your home. Electrical panel replacement costs fall between $400 and $2,500. Most homeowners will pay somewhere in the middle of this price range for a 200-amp panel.

If you need to open walls to run wires through your home, the cost to knock down walls falls between $0.40 and $6.40 per square foot. Load-bearing and stone walls cost the most to open, as they require more skill and costly replacement materials, while drywall is a fast and simpler material to open and replace.

Wiring a new house may be cheaper than rewiring an old house. Newer homes typically have easier layouts for accessing wires and installing new ones into the wall. Additionally, older homes can come with many hidden surprises, as building regulations have changed over the decades to make it easier for electricians to access the walls.

As one of the more affordable types of wiring for a home, THHN or THWN wire costs between $0.15 and $1.50 per foot on average. Also called thermoplastic, high heat-resistant nylon-coated (THHN) wire and thermoplastic, heat-resistant, water-resistant nylon (THWN) wire, these materials contain a single conductor, insulation and a jacket to protect the wires. Their affordability makes thempopular in many homes.

Your safest option is to hire a licensed electrician to rewire your house instead. An electrician near you has the experience to safely complete the job.

If possible, have your pro pull old wires through your crawlspace, attic, basement or floor joists rather than through breaking down walls. Many electricians can fish wire through the walls of your home to avoid costly wall repair services. If you must access wires through the wall, try to have the project completed in one go to avoid having to re-open walls.

To arrive at the average costs in this article, editorial team members surveyed 16 different providers on national and local levels. All averaged figures were correct at the time of publication and may be subject to change.

The best homeowners insurance companies may cover rewiring in your home, but this is not always guaranteed. If you attempt to rewire your home yourself and then stumble upon wiring problems, this will typically void any insurance coverage. Always read the fine print of your homeowners insurance to see if the plan covers rewiring your house.

How long it takes to rewire your house depends on the size of the property, the extent of the rewiring and accessibility. Old houses that have hard-to-reach access points for rewiring can take a week to 10 days to complete, while newer homes that need only minor rewiring can take three days.

Electric utilities use electric meters installed at customers' premises for billing and monitoring purposes. They are typically calibrated in billing units, the most common one being the kilowatt hour (kWh). They are usually read once each billing period.

When energy savings during certain periods are desired, some meters may measure demand, the maximum use of power in some interval. "Time of day" metering allows electric rates to be changed during a day, to record usage during peak high-cost periods and off-peak, lower-cost, periods. Also, in some areas meters have relays for demand response load shedding during peak load periods.[1]

The earliest commercial uses of electric energy, in the 1880s, had easily predictable usage; billing was based on the number of lamps or motors installed in a building.[citation needed] However, as usage spread, and especially with the invention of pluggable appliances, it also became more variable, and the electric utilities sought a means to bill customers based on actual rather than estimated usage.

Many experimental types of meter were developed. Thomas Edison at first worked on a direct current (DC) electromechanical meter with a direct reading register, but instead developed an electrochemical metering system, which used an electrolytic cell to totalise current consumption. At periodic intervals the plates were removed and weighed, and the customer billed. The electrochemical meter was labor-intensive to read and not well received by customers.

DC meters often measured charge in ampere hours. Since the voltage of the supply should remain substantially constant, the reading of the meter was proportional to actual energy consumed. For example, if a meter recorded that 100 ampere hours had been consumed on a 200-volt supply, then 20 kilowatt-hours of energy had been supplied.

An early type of electrochemical meter used in the United Kingdom was the 'Reason' meter. This consisted of a vertically mounted glass structure with a mercury reservoir at the top of the meter. As current was drawn from the supply, electrochemical action transferred the mercury to the bottom of the column. Like all other DC meters, it recorded ampere hours. Once the mercury pool was exhausted, the meter became an open circuit. It was therefore necessary for the consumer to pay for a further supply of electricity, whereupon, the supplier's agent would unlock the meter from its mounting and invert it restoring the mercury to the reservoir and the supply. In practice the consumer would get the supply company's agent in before the supply ran out and pay only for the charge consumed as read from the scale. The agent would then reset the meter to zero by inverting it.

In 1885 Ferranti offered a mercury motor meter with a register similar to gas meters; this had the advantage that the consumer could easily read the meter and verify consumption.[2] The first accurate, recording electricity consumption meter was a DC meter by Hermann Aron, who patented it in 1883. Hugo Hirst of the British General Electric Company introduced it commercially into Great Britain from 1888.[3] Aron's meter recorded the total charge used over time, and showed it on a series of clock dials.

The first specimen of the AC kilowatt-hour meter produced on the basis of Hungarian Ott Blthy's patent and named after him was presented by the Ganz Works at the Frankfurt Fair in the autumn of 1889, and the first induction kilowatt-hour meter was already marketed by the factory at the end of the same year. These were the first alternating-current watt-hour meters, known by the name of Blthy-meters.[4] The AC kilowatt hour meters used at present operate on the same principle as Blthy's original invention.[5][6][7][8] Also around 1889, Elihu Thomson of the American General Electric company developed a recording watt meter (watt-hour meter) based on an ironless commutator motor. This meter overcame the disadvantages of the electrochemical type and could operate on either alternating or direct current.[9]

In 1894 Oliver Shallenberger of the Westinghouse Electric Corporation applied the induction principle previously used [10] only in AC ampere hour meters to produce a watt-hour meter of the modern electromechanical form, using an induction disk whose rotational speed was made proportional to the power in the circuit.[11][12] The Blthy meter was similar to Shallenberger and Thomson meter in that they are two-phase motor meter.[5] Although the induction meter would only work on alternating current, it eliminated the delicate and troublesome commutator of the Thomson design. Shallenberger fell ill and was unable to refine his initial large and heavy design, although he did also develop a polyphase version.

The most common unit of measurement on the electricity meter is the kilowatt hour [kWh], which is equal to the amount of energy used by a load of one kilowatt over a period of one hour, or 3,600,000 joules. Some electricity companies use the SI megajoule instead.

Reactive power is measured in "thousands of volt-ampere reactive-hours", (kvarh). By convention, a "lagging" or inductive load, such as a motor, will have positive reactive power. A "leading", or capacitive load, will have negative reactive power.[13]

Distortion of the electric current by loads is measured in several ways. Power factor is the ratio of resistive (or real) power to volt-amperes. A capacitive load has a leading power factor, and an inductive load has a lagging power factor. A purely resistive load (such as a filament lamp, heater or kettle) exhibits a power factor of 1. Current harmonics are a measure of distortion of the wave form. For example, electronic loads such as computer power supplies draw their current at the voltage peak to fill their internal storage elements. This can lead to a significant voltage drop near the supply voltage peak which shows as a flattening of the voltage waveform. This flattening causes odd harmonics which are not permissible if they exceed specific limits, as they are not only wasteful, but may interfere with the operation of other equipment. Harmonic emissions are mandated by law in EU and other countries to fall within specified limits.

In addition to metering based on the amount of energy used, other types of metering are available. Meters which measured the amount of charge (coulombs) used, known as ampere hour meters, were used in the early days of electrification. These were dependent upon the supply voltage remaining constant for accurate measurement of energy usage, which was not a likely circumstance with most supplies. The most common application was in relation to special-purpose meters to monitor charge / discharge status of large batteries. Some meters measured only the length of time for which charge flowed, with no measurement of the magnitude of voltage or current being made. These are only suited for constant-load applications and are rarely used today.
