Indoor and outdoor electrical panels work in the same way and cost the same. However, those placed outside are weatherproof or weather resistant. That means they are less likely to be damaged by rain or freezing conditions. An outdoor electrical box may be installed for outdoor structures, such as barns, gazebos, saunas, or pools.

Many areas have regulations that require an outdoor electrical panel installation of the unit. This allows firefighters to turn off power to the home if necessary. Homes built after 2000 typically have exterior systems. If a house has an existing panel inside, it is most likely that a new replacement unit will be placed in that same location outside. If there is one outside, which is common in newer homes, replacing it will be done in the same location. Keep in your mind that electrical boxes and electrical panels refer to the same thing, the metal housing for the electrical system.

If you want to move your indoor system outdoors, it requires full home electrical rewiring. To do this, the electrician would remove the existing system with all wiring. Then, they would install the new box outdoors and run the wiring again through the house. This would essentially double the cost of installing a box in the same place. Expect to pay the amount between $5,000 and $12,000. There may not be a valid reason to do this other than to make the box more accessible.
