That means there isn’t necessarily capacity to add an additional 100-amp subpanel.
However, many modern-day homes can already use close to 200 amps. In most cases, you’ll install the subpanel near the main one.Īdding a Subpanel For example, if you have 200-amp main service, you’ll have no problem adding a 100-amp subpanel to feed a shed, garage, or barn. Models have 4 to 20 or more circuits, and the amperage ranges from 100 to 150 amps. This depends on the amperage and the number of circuits. Subpanel Installation Cost The cost to install a subpanel is $400 to $1,750.
Can I add a 100 amp sub panel to a 200 amp service?.
