A main panel is the first line of defense against the electric surges and other faults short circuit , overload, over current etc. The main panel is directly connected to the feeder cables from the energy meter and distribution transformer mounted on the utility pole. In residential applications, three wires i. The two hot wires i. A subpanel Remote Panel in NEC is a smaller service panel derived from the main panel via two poles circuit breakers to securely distribute electric power to the other parts in the building, home, garage or any other specific applications in the premises. A subpanel does the same job as the main panel i. Keep in mind that there is no need to bond Ground with Neutral in the subpanel as they are already bonded in the main panel.

How big should your Sub-Panel be? Watts and Amperage This will help you consider the circuits to be served by the Sub-Panel including general purpose electrical outlets and any special equipment which will be needed. Special Considerations: Large Volt Loads such as Welders, Air Conditioners, Motors, Well Pumps and the like may require larger size wire and conduit to provide the necessary current this equipment requires. Be sure to list all the label requirements and manufacturers specifications. Long Distances from the power source will produce Voltage Drop, especially over feet. Don't Make This Mistake! I fed this sub panel with 10 UF cable. From this sub panel, I am feeding 2 — 20 amp circuits with 14 wire. With nothing but the fluorescent lighting on, I pull about 2. When I turn on my shop vac however, I am pulling about 11 amps of current, and my measured voltage on this circuit drops to volts.
