Electrical Wire

Whole House Rewire

Access to electricity in our homes is one of the many conveniences of modern life, but this convenience presents a constant threat to our welfare. Electricity causes over 40,000 housefires each year in the US, and the leading culprits are old switches and receptacles.

Every switch and receptacle contains multiple points of connection with wires. Wires vibrate as electricity passes through them, generating heat, which loosens the connection between the wire and the device over time. This loose connection allows arcing to occur between the wire and the device connection point. The heat produced during arcing melts devices and ignites combustibles, causing house fires.

Switches and receptacles are tested by the Underwriter Laboratories for reliability and robustness for up to 10 years. Many devices last longer than 10 years, but realistically manufacturers have no incentive to produce a higher quality receptacle than the minimum needed to get UL listed. Because of this, it is advisable to replace devices that are over 10 years old, rather than risk a deteriorating device failing and igniting combustibles.

A Whole House Rewire is recommended when all of the devices in a house are old, or if the house was built with low-quality builders grade devices that often fail within 2 years of installation. During a Whole House Rewire, every receptacle and switch in the home is replaced with a brand new device. The process takes 1-2 days and power remains on throughout the house, with brief interruptions on circuits being directly worked.

Rewiring a home as devices get old is part of good maintenance, much like changing the brakes on a car to prevent rotor damage. Hazardous situations occurring behind devices are discovered and rectified before they have a chance to damage property or endanger lives. The safety of the home is further increased by the installation of new tamper-resistant receptacles, required by the current NEC, which contain a mechanism that prevents children from sticking objects into the receptacles.

A Whole House Rewire improves the home’s value, safety, and functionality, while also mitigating future service call fees and inconvenient power disruptions as old devices inevitably start failing.

Electric Car Charging Station Installation

The best place to charge your Tesla/Electric Car is at home, overnight

Pull into your normal parking spot, plug in, and you will wake up to a full charge every morning. To prepare your home for charging your vehicle, hire Nova Construction Proc to install a dedicated circuit convenient to where you will park your vehicle. A licensed electrician from Nova Construction Pro will need to visit your home to provide a quote for charging equipment installation. Cost of installation will vary by location, cost can range from a few hundred to a few thousand dollars, depending on the scope of work. Some homes may require service panel upgrades or trenching to install home charging equipment, increasing the cost.

Nova Construction Pro recommends the Wall Connector as the most convenient home charging equipment for Electric vehicles. Permanently mounted to a wall or post, the Wall Connector can be installed both indoors and outdoors. A defining feature is the ability to be installed with any circuit breaker ranging from 15 to 100 amps, which allows the Wall Connector to be custom fit to almost any electrical system. We recommend installing the Wall Connector with a power output to match the on-board charger of the vehicle, typically a 4060 or 90 amp circuit breaker.

Why Level 2 Wall Connector is Best for Home Charging

240V level 2 chargers provide a bigger “pipeline” for electricity to flow to your Tesla. They can charge up to 15 times faster than trickle chargers. Tesla Mobile Connector, Wall Connector and the wireless Tesla charging station are different types of Level 2 chargers. A “Level 2” EV charger is simply any EV charger that can connect to a particular type of electrical circuit — 240 volt, split phase circuits (similar to what an electric dryer uses).

The ideal home Tesla charger offers these benefits:

  1. Recoups your daily driving range in just a few hours
  2. Fully recharges your battery overnight on the occasions that you arrive home on low charge (after a long trip, etc)
  3. Doesn’t require major upgrades to your home electrical service

For US drivers who cover about 37 miles per day on average, a charger that delivers 20-30 miles of range per hour charged is ideal (6.6-10 kW power delivery). Average daily miles are recharged within 2 hours and even a close-to-empty 100 kWh battery can be charged fully overnight. For the vast majority of homes, charging at those speeds will not require major electrical service upgrades to 400 amps.
