We have a Gazebo (concrete slab approx. 50x20) to wire that will have few lights and receptacles. It will be used for people to have parties, BBQS, etc. To stay code compliant, is it OK to run 2 - 20 amp ckts. out to the structure, or do I have to install a 2ckt. sub-panel at the structure. All sides are open on this patio and the breaker panel that I will run the ckts. from is approx. 50' away. I was going to go with a sub- panel, and another Elec. said I did not need it. Thanks for the input.
