NEC requirements for conduit bending, support spacing and grounding

Conduit bending: The NEC sets a maximum of four 90 degree bends or 360 degrees total in one conduit run. It also gives the minimum bend radius for each conduit type and size. For instance, a 90 degree bend for 1/2 inch EMT conduit must have a 4 inch radius.

Support spacing: The NEC mandates that conduits be fastened securely every 3 feet or less and within 3 feet of any box, cabinet, or fitting. Some conduit types and methods have different rules. For example, rigid metal conduit can be supported every 10 feet if it is threaded and coupled or in threaded fittings.

Grounding: The NEC requires that electrical systems and equipment be grounded to create a low-impedance path for fault current and to keep the voltage stable. It also requires that metal parts of electrical equipment, such as boxes and raceways, be bonded to ensure electrical continuity and conductivity.

What electrical pipe fitting sizes are available?

The most common sizes of electrical pipe fittings carried by LiveWire are:

1/2 inch (16 mm)
3/4 inch (21 mm)
1 inch (27 mm)
1-1/4 inch (35 mm)
1-1/2 inch (41 mm)
2 inch (53 mm)

Some electrical pipe fittings can also connect or adapt different sizes or types of raceways, such as reducers, enlargers, adapters or bushings.
The size of electrical pipe fittings should match the size of the conduit and the wires that run through them. The National Electrical Code (NEC) specifies the maximum fill allowance and requirements for different types of conduit and wire.
