An improved electrical receptacle box has resealable openings and adapted to enclose an electrical apparatus such as a five-wire receptacle. Wall receptacle boxes are used to mount standard electrical switches or duplex plug-in receptacles.
In a house there are many receptacle boxes installed. Since, their purpose is vital, they should be chosen wisely. Below are some of the factors one should consider while having them for your place.
Make sure your box is deep enough to avoid crowding the wires. It must be deep enough so a switch or receptacle can be installed easily without crimping or damaging the wires. But, ensure you do not purchase the box that is of the size bigger than the wall thickness.
Moreover, the overall size of the box should be of correct size. Using a box that's too small, results in a problem known as "cable fill violation", which is not only a code issue but also, a potential safety risk.
Made from both plastic and cast metal, weatherproof boxes are used outside the house when the entire receptacle box will be exposed. Even though the box is weatherproof, the receptacle still needs to be protected with the weatherproof cover.
Look for the right material for every particular place. Plastic electrical boxes are the most widely used boxes for indoor residential wiring. They're inexpensive and easy to install. However, since you cannot ground a plastic box, so some local codes do not allow them or they are only allowed for certain uses. Metal electrical boxes are stronger and provide better ground connection than plastic boxes.
Moreover, plastic receptacle boxes should not be used with the heavy light fixtures and fans. Well, the metal boxes are best suited for such purposes.
Electrical work should only be performed by a confident, experienced person or by a licensed electrical contractor. Never work on live circuits. Before work begins, the circuit should be identified and turned off at the panel. |
