Conducting a load calculation on a single or multiple family dwelling involves a few steps
As master electricians we are educated and tested on our abilities to read the code and apply it in situations like this.
For example, your standard home range is rated for 12-14,000 watts each. However, we don’t apply that number directly to the demand of the home, we only apply a portion of it, a percentage to be exact. Then we tack on the other heating and air conditioning loads, any electric water heaters, spas, and hot tubs, electric kilns, electric dryers, saunas, large consumption dishwashers, big electric tools, etc.
We then also use the square footage of the home to decide what the demand of all the basic receptacles, and lighting in the home with use.
Once this is all calculated and added together we can find out what the demand load on your home’s service installation is. If you have a 60A service, when the home was built, the calculated load would have been 59.999999 amps, or less. That would give you a requirement for the 60a service.
Should the calculation come out to 60.0001 amps, or more, then the next available size service of 100a would need to be used, or higher, should the calculation be above the next size available.
Factors Considered in Electrical Load Calculation
Factors that are considered during the electrical load calculation process include:
- The power consumption of individual devices and appliances
- The total number of devices and appliances in the home
- The capacity of the existing electrical system
- The overall layout and design of the electrical system
- The requirements of the City of Edmonton
Some challenges and limitations include:
- The complexity of electrical systems in modern homes
- The potential for inaccuracies or mistakes, especially without professional assistance
- The need to stay updated on local regulations and requirements
