Circuit Breaker Panel is a low voltage distribution board that is commonly used to serve and protect utility loads. These loads may significantly impact the overall electrical distribution network and therefore shall be properly powered, protected and maintained. Electrical professionals design panel schedule documents in projects with certain requirements for panel fabrication and load protection. Watch this video featuring Intergraph SmartPlant Electrical in action to produce a low voltage circuit breaker panel schedule.

About a week after i turned on my refrigerator i started getting a burning smell from the breaker box and needed a quick fix since i had food stored. I could not find a place in town that had RV breaker boxes so i went to the home depot and picked up a sub panel and some heavy gauged wire to make extensions to relocate the breaker switches.
