The maximum length of conduit used as a raceway can vary depending on the type of conduit and local electrical codes. Generally, there are no specific maximum lengths for conduit itself, but there are guidelines for the number of bends and the overall circuit length. For example, the National Electrical Code (NEC) allows for a maximum of 360 degrees of bends in a conduit run without requiring a pull point. Always consult local codes and regulations for specific requirements.

To determine if you can fit six 350 MCM wires in a 3-inch conduit, you need to refer to the NEC (National Electrical Code) conduit fill tables. Generally, a 3-inch conduit can accommodate a limited number of large conductors, and 350 MCM wires may exceed the maximum fill capacity. It's essential to check the specific conduit fill calculations and local codes to ensure compliance and safety.
The maximum length of sealtight flexible metallic conduit (also known as flexible metal conduit or FMC) is typically limited to 6 feet for a single run without any fittings, as per the National Electrical Code (NEC). However, longer runs can be accommodated with the use of appropriate fittings and supports. It's essential to check local codes and regulations, as they may impose additional restrictions or requirements.

The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.
The maximum allowable fence height extension in this neighborhood is six feet.
The maximum allowable height for a person's photo on a passport is 2 inches.
The maximum allowable linear dimension of baggage for this flight is typically 62 inches.
The maximum percentage allowable is 65 percent. This can only be taken out if the garnishee does not support a second family and owes more than 12 weeks of back child support. If the garnishee does support a second family, the maximum is 55 percent if he owes more than 12 weeks of back child support, and 50 percent if he does not.
The maximum allowable passport photo height for it to be considered valid is 2 inches.
The PVC conduit fill chart provides information on the maximum number of cables that can be safely installed in a conduit based on the size of the conduit and the diameter of the cables.
