How Many Watts Can A 20o Amp Service Delivet

Do y'all demand a 200 amp service for your electric automobile? The previous Ontario authorities thought then. They passed legislation requiring all new homes to take a 200 amp panel. But this was overturned by Doug Ford in May. And then do y'all need 200 amps or non? It's a tough question and depends on the equipment currently installed in your home. And if yous have plans for any other big electric additions similar a hot tub.

The electric service explained

First I'll give you an caption virtually what exactly the 'service' is, be it 100, 200 or fifty-fifty 400 amps. Homes in North America are wired almost exclusively using unmarried phase electricity service consisting of ii hot wires of 120 volts each and a neutral wire. The two hot wires when used together provide 240 volts for appliances like stoves and clothes dryers.

These three wires come up from the street, either underground or from a utility pole, and enter your hydro meter on one end. The hot leads are metered while the neutral is not. The two 120 volt wires exiting the meter claw up to your panel main breaker. The un-metered neutral wire is continued to neutral charabanc bars in the panel and doesn't crave a breaker.

The electric current your home uses when you turn on lights or run appliances is measured in amps. And the size of your service is expressed in amps as well. A 200 amp service can evangelize twice every bit much current every bit a 100 amp service. To safely evangelize this extra power the bigger service needs a larger capacity main billow and thicker wires when compared to the smaller sized service.

But many homes use a 100 or 125 amp service because that was the requirement at the time they were built. Which begs the question, do you really need a 200 amp service for charging your electric car?

Figuring out what you demand

Figuring out the size of the service and main breaker needed to accommodate an electric automobile charging port isn't piece of cake. You'll also need to ensure that you have the correctly sized wiring from the meter to the main electrical panel. And these are of import considerations if you are planning to add any equipment that draws a lot of power.

The calculations are best left to the professionals. The Canadian Electric Lawmaking (CEC) has a lot of rules, regulations and exceptions that need to be applied. The code uses a combination of watts per square foot and the electric load of various appliances and equipment in the abode to determine the correct service you should be using.

Luckily I found a somewhat dated article with the calculations. The regulations on charging stations have loosened upward a bit since the mail service was published. Beingness I'one thousand not an electrician I needed something to work from so I used their chart on my home simply to demonstrate how this works.
