For all of the do-it-yourselfers out there, you can install a junction box over the course of a few hours. But before getting started, determine the exact type of box you want to install. Options include a waterproof, electric, or outdoor box. For an outdoor version, consider getting a weatherproof box.
Make sure to purchase the correct junction box size according to your power requirements. Install an electric box and get ready for all of your power needs.
