6-Factors Why You Should Install an Electrical Subpanel In Your Home by Add On Electric

You may already be familiar with the main panel, which is in a house and is responsible for carrying the total electrical load. Your home’s primary electrical panel, a circuit breaker, is where electrical current first enters your property. Why bother learning about subpanels if you already have the main panel that does the whole work? What precisely are these things called subpanels?

To put it another way, a subpanel is a panel that is smaller than the panel that serves as the primary panel. It assists in distributing power to various locations within your home. It is also referred to as a satellite circuit breaker, and it receives its power from the main panel via a circuit breaker with a double pole and 240 volts. At the subpanel, it is separated into a variety of branch circuits and features independent breakers.

While your primary electrical panel might have sufficient room to accommodate the house’s wiring, this does not always guarantee it is safe. People choose to install a subpanel for several reasons, including that it lessens the strain placed on the main panel and raises the overall degree of safety. A packed main panel is a potential catastrophe waiting to happen, so it is a good idea to invest in a subpanel, as recommended by licensed electricians, as this may be a costly mistake.

The subpanel or the central panel can be directly adjacent to the main electrical panel. Alternatively, the subpanel can be in the room where you wish to split the electrical power usage.

The Main Panel Vs the Subpanel: Differences and Comparisons

You won’t immediately grasp the distinction between the main panel and the subpanel. The central panel serves as the point of entry for the electrical power and is also responsible for electricity distribution to various parts of your home. On the other hand, a subpanel performs the functions of both a central panel and a small panel in that it also distributes energy; nevertheless, it is not where electric power enters your home.

A circuit feeder is used to make the connection between the main electrical panel and the subpanels. A subpanel cannot boost the power supply on its own or create additional power, which is one of the primary distinctions between the two.

The primary reason is that they are wired into the main supply and derive their power from that source. In light of this information, a subpanel may be understood as an extension of the main panel.

Why should you choose to install a subpanel in your home?

Subpanels are highly recommended by electricians in Vancouver to professionals and homeowners alike for various reasons. You will need to hunt for an electrician in the area if you want to install a subpanel.

It would help if you considered installing a subpanel for all of the following reasons:

This may bring about a great deal of trouble. An electrical contractor who assists you may require you to buy a sub panel and have it put so that it is simpler for them to traverse.

If you install new lights or a baseboard heater, you may be required to provide an independent circuit. However, this will not be possible if your main panel is already complete with other appliances and devices.

Over Wiring

A shortcut can be achieved by using excessive wire. Users can obtain more power from the main breaker panel. There is a type of circuit breaker known as a tandem breaker that enables two separate circuits to share a single slot. This can be challenging, but it is not always a threat to the power supply immediately away.

Circuit breakers differ from double-pole breakers requiring a single slot to function correctly. Overwriting is considered illegal in several different localities. To avoid the violation and the repercussions that come with it, households must build subpanels and cease overloading the main panel with additional lines.

Alterations Or Extensions to The Building

It’s possible that you’ve expanded your home to include additional rooms or are considering constructing a second garage. You must be aware that any improvements or additions you make will harm the primary control panel of your building. It is preferable to keep the weight off it because you already have a sufficient load on it.

Installing a subpanel is the most effective method for relieving strain on the primary panel. If an electrician uses this subpanel, it will be much simpler for them to wire the additional spaces that have been added.

In addition, it is preferable to position the panel near the additions so that it will be less difficult to distribute the electricity. Electricians can keep the electric subpanel as orderly and streamlined as feasible.

Independent Real Estate

You may own other property in addition to the one you already own. You may not have direct use of this independent property, but it does have the potential for other applications. For instance, it might be a rental home or serve some purpose unrelated to the costs of maintaining your primary residence. Other possibilities include It is highly recommended that you acquire a subpanel that may assist you in maintaining disparities if your building has a distinct unit.

Despite its size, the additional unit likely contains several appliances with significant power consumption and the potential to overwhelm the primary unit. It is recommended to have a separate panel for these appliances since they have different needs for electrical power usage. As a result, it will be much simpler to handle everything if you do so.

Many people launch various enterprises from within their houses, which might influence their primary circuit. Because of this, it is best to keep the electricity your company uses separate from the electricity you use in your house. You may install the new wiring by hiring an electrician in Vancouver, and the subpanel can distribute the load.


A subpanel next to the additional space or the new outlet is likely convenient for you. Thanks to this, it won’t be challenging to access the panel whenever the circuit breaker trips. In addition, most of the primary panels are often located in the basement or the attic, which are notoriously difficult to get to.

Because of this, having a subpanel located on the same floor as where you live might make it extremely easy to reach it, and you won’t have to travel down to the basement or up to the attic to replace your circuit breaker.

If you have outbuildings, you may obtain a subpanel for them so that you can access the electricity through the subpanel, and this is something you should do.


The situation may become dangerous if many cables are connected to the same circuit. There are a lot of electricians in Vancouver who believe that having a sub-panel is the best way to ensure safety. It is advisable to have a backup plan and to always have the subpanel within reach since there is a possibility that the main panel will be located outside the structure. Thanks to this, you will have easy access during an evacuation, a fire, or any other type of disaster.

You may also switch off the electricity by using the subpanel, in which case you do not need to worry about accidentally electrocuting yourself.

In addition, it is essential to have reliable power regulation across your home to ensure that there is no power surge and that things are made easier to control.
