When you are constructing a house or redesigning your home and have to design the electric panel board there are many things that you have to take into consideration. The function of the main electrical panel is to distribute electric power to the various appliances and fixtures in the house. This distribution is done with the aid of electrical circuits that emerge from the panel. As a general guideline, it’s best to keep these few materials handy before designing the panel.
Step 1 - Understand Components
Electric panels can be customized and configured to meet the power requirement of the household. This is why there are different dimensions. Before designing an electrical panel board, it is good to know its components. The main panel distributes electricity to the household through branch circuits. These then go to the switches, appliances, and other receptacles throughout your home.
Step 2 - Understand the Circuits
Two copper aluminum strips under the circuit breakers and the wiring panel are the power buses or hot buses that are connected to the incoming cable. Both the neutral and the wires for grounding are connected to their respective buses. These are present on either side of the power buses. The main breaker which controls all the power in the house is located on the upper part of the electric panel.
Step 3 - Consider Power Requirements
An electric panel in a house provides 100 or 150 or 200 amps. The individual circuits are then distributed from the main breaker by individual breakers which branches the power throughout the home. These individual breakers are designed depending upon the requirement of power. A light outlet circuit would need 15 amps and other appliances that need more power would usually be 60 to 100 amps.
Step 4 - Design the Panel
When you create the design for your electric panel the following details should be incorporated into it.
Location and dimension of the panel
Load description, amperage, and voltage required
Phase and NEMA type
Horsepower, cable size, and conduit size
Indication of the home run circuitry with a designated number
Number of wires a conduit carries
Type of insulation
Step 5 - Combine Location and Design
If the panel is to be placed in an environment that you think could be polluted, design it to keep contaminants out by applying positive air pressure. If it is to be placed in a dark area, design it to have an internal panel light mounted on it. On the other hand, design the panel to have a drain hose at the bottom of its enclosure if it is going to be installed in a place where water or other liquids may enter its enclosure.
While it is wise to take into account all the power needs of the house, it would be wiser to future proof your home when designing an electric panel. With advances being made in technology and electric power being the source that runs many appliances, you must design the panel to take care of the future power needs of your home.
