breaker box outdoor. Condition is "Used". Shipped with USPS Parcel Select Ground. Square D homeline breaker box. The steel box is indoor or outdoor use. It will use either 2 120 volt breakers or 1 240 volt double breaker up to 50 amps. We bought three of these to install for a pool heater and ended up adding the breakers to the house breaker panel. THERE ARE BREAKERS INCLUDED WITH THE BOX. Please feel free to ask any questions prior to purchasing and we will be glad to help you.
