When mounting a panel box, there is a height restriction. The circuit breaker at the top of the box must be no higher than 6 feet 7 inches from the ground. If the top circuit breaker exceeds this height, a permanent platform must be installed beneath the panel box.
The National Electrical Code requires that all panel boxes be set on a permanent foundation. This foundation may consist of cinder blocks, concrete blocks, or another solid material that will not move under load conditions. The code also requires that all metal panels be grounded to prevent corrosion and provide a path for electricity to leave the building.
Panel boxes are available in several sizes depending on the number of circuits you plan to carry. The standard size is 100 amp capacity, but 240-amp versions are also available. Large utility companies often supply their own panels, while smaller ones must purchase them in bulk from a manufacturer. A panel installation should be done by a qualified electrician.
A wiring diagram is required by law when connecting up more than one circuit. These diagrams show which wires go where so that nobody gets hurt. They are usually included with your home inspection report if you are buying a house already built. If you are building a new home, the builder should provide one with his/her plans.
Circuit breakers protect the wires inside the panel box from damage due to high current flow.
A circuit breaker box is a closed receptacle that houses several breakers and an identifying panel. As a result, "circuit breaker panel box" is a typical term for this box. The panel box can be located either outside or within the home, at the entrance point of the wire conduit. In most cases, panel boxes cannot be installed higher than 48 inches above ground level. Exception: If the box is mounted on a factory-built house or unit, then it can be placed at any height.
The panel box should be positioned so that it does not impede entry to the house or access to other equipment (such as a meter) that may be needed in the future. Boxes are available in various sizes and shapes. But generally they fall into two categories: single-gang and multiple-gang. A single-gang box can only hold one breaker. A multiple-gang box can hold up to three breakers, but most have provisions for holding four or more breakers. Heavier duty circuits need heavier duty components to withstand greater current levels. The manufacturer of your box will be able to help you determine what size breakers should be used for your application.
Circuit breaker panels are available with different operating methods. Single-pole switches operate by connecting and disconnecting just one conductor from the power source. Three-phase switches connect all three conductors together and disconnect them from the source simultaneously.
All electrical panels must have a minimum of 36 inches of clearance in front of the panel, 30 inches of space across the face of the panel, and 78 inches of clearance from the top edge of the panel to the floor. The distance between panels must be equal to or greater than the width of the vehicle.
The location of your electrical panel is determined by the type of application you are working on. If you are installing a new circuit, then the best location for an electrical panel is near the center console of your car. This will give you access to all parts of the circuit with one simple connection. If you are replacing a fuse box, then you should locate the panel in an accessible area of the engine compartment. Make sure that you leave yourself enough room between the edges of the panel and any vehicles components (such as radiators) for wiring adjustments and maintenance.
The height of your electrical panel is based on how much space you have above it. If you do not have enough space, then you will need to install your panel in a location where it can be later raised up onto scaffolding or other building materials.
In conclusion, the height of your electrical panel is based on the size of your project and the location where you plan to mount it.
