The electric panel has the hardest job in any home, as its' smooth functioning is essential to the safety and satisfaction of the daily routine. An electric panel is a connection between your home and your utility company, as it distributes electricity to your appliances through major as well as smaller electrical connections.

With that in mind, RenoQuotes.com is here to help you know when and how to upgrade your electric panel to keep your home, as well as your family, safe.

Does my Electric Panel Need Updating?

So, you're not an electrician, but how can you tell if your panel needs updating? There are several telltale signs that you should look out for:

•  crackling sounds coming from the panel itself, 

• corrosion or rust on breakers, 

• overheating of appliances, 

• needing surge protectors to protect them.

On average, the panel has a lifespan of 25 to 30 years, though, with the rapid development of technology, older panels won't hold up against the appliances of today. 

It often occurs that your insurance company will push for an update to make sure your home is safe from the risk of fire. Another reason for updating your electric panel may be because you are undergoing a home renovation of sorts. Specifically, if you are adding new, or more technologically advanced, appliances to your kitchen or garage.

In this case, it is recommended that you consider upgrading to a panel that can function properly with all appliances running. As we've already stated, updating your panel not only makes things run smoothly, but it has a considerable effect on the safety of your family. It is suggested that you speak with a trained professional regarding whether your electric panel could use an update.

Upgrading Your Electric Panel

Now that you've concluded that your electric panel needs to be upgraded, how do you move forward with the transition? Labour and material costs will vary greatly, and depend on the condition of the current electrical panel, including what condition wires and conduits are in as well as whether you require new sub-panels.

In Canada, the Canadian Electrical Code or the CEC uses a "demand calculation" to determine the minimum size that your electrical service should be. This calculation should be completed before you move forward with any sort of upgrade on your electrical panel. The information the CEC collects is used to determine whether your home requires a panel change or a service upgrade. Also make sure to be aware of the specific regulations or policies that may arise from a local code or by-law, as well as your insurance company.

A panel update generally determines that the service is in good shape, but you may need to change your panel to accommodate additional circuits or specialty breakers, which require renewed grounding and bonding.

1. Sever all wires inside the electrical panel with diagonal-cutting pliers,  

2. Unscrew and remove the old panel from the wall. In order to support the new panel, it is recommended that you attach a 3/4-inch-thick plywood panel to the wall. 

3. Feed the service entrance (SE) cable through the top of the new electrical panel and attach the panel itself to the plywood. Next, you can go ahead with securing the electrical connections inside the panel. 

4. Feed the house circuits into the panel, making sure each cable is passing through a cable connector. 

5. Connect the bare-copper wires and white-insulated wires to the ground and neutral bar,  

6. Plug new circuit breakers into the bus bar. 

The main ground wire must be run from the bottom of the new panel to the copper water main. Now, all that's left is for your utility company to reconnect the electrical cables to the exterior of the house!

Some other things to remember when updating your electrical panel is that the power will be out for a minimum of 4 or 5 hours, so make sure to unplug all electronics and keep fridge and freezer doors closed! If you do not feel comfortable completing the updates yourself, or are looking for a second opinion, it is recommended that you talk to a variety of electrical contractors to get a better idea of what you're working with!
