What is an Electrical Subpanel?

An electric sub panel is an additional electrical panel that is installed to increase the capacity of the main electrical panel. It is used to allow for more circuits to be added to a home or commercial building. It is typically located in a separate area from the main panel and can have individual circuit breakers for each branch circuit. It is a crucial part of the electrical system and when it comes to outbuildings; it is even more important.

An electrical sub-panel is typically installed in an outbuilding, such as a shed or garage, to provide additional power and safety to the garage, shed or pole barn. This allows for a separate power source from the main panel, which can help protect the home from power surges and outages. It also provides an outlet for additional electrical appliances and devices that may not be connected to the main panel.

When it comes to buying an electrical sub-panel for an outbuilding, there are several options available. Homeowners can purchase sub-panels from their local home improvement stores such as Lowes and Home Depot.

The cost of a sub-panel will vary depending on the size of the panel and the type of panel that is purchased. Generally speaking, they can range from a hundred dollars to as much as $350 depending on the size and type of panel that is purchased.

What Should I Consider When Purchasing an Outbuilding Electrical Subpanel?

When purchasing an electrical sub-panel, there are several factors that should be taken into consideration. First, homeowners should make sure that the panel is rated for the amount of power that will be used in the outbuilding. This is important to ensure that the panel is not overloaded and will be able to handle the electrical load.

Second, homeowners should make sure that the panel is installed by a qualified electrician or electrical contractor. This is important to ensure that the panel is installed correctly and meets all local electrical code requirements.

Finally, homeowners should make sure that the panel is compatible with the wiring in the home and that it is UL-listed. UL-listed panels are designed to meet the highest safety standards and are the safest panels available.

What size subpanels are there?

If you’re wondering what size subpanel to install in your workshop, the answer depends on the electrical power draw and the type of equipment you’ll be using. The minimum size for a sub panel for a workshop should be 60 amps, and up to 100 amps if you have a 200 amp primary service. It should also be a 120/240 volt single phase panel. Add more amps if you need more power.

For a shed a 60 amp sub-panel would be more than enough, however if you are wiring a garage or pole barn or plan on using a welder, large air compressor or a similar type of tool that needs lots of power than opt for 100 amp subpanel.
