Here is an example :
Today I am tasked with installing a Hot Tub and the electrical requirement is minimum 6 awg wire size. Looking at some flexible tubing to run from the breaker to the tube i needed to get a size, here is the interaction
What is the minimum inside diameter for flexible conduit to house 3 6awg wires
To determine the minimum inside diameter of a flexible conduit for housing three 6 AWG wires, we need to consider the NEC (National Electrical Code) guidelines for conduit fill.
The NEC provides a table for conduit fill calculations. For three 6 AWG wires, the total conductor area is as follows:
- 6 AWG wire has a diameter of approximately 0.162 inches.
- The NEC recommends 40% fill for conduit (standard practice).
Step 1: Calculate the total area of the wires
From NEC Table 8, the approximate circular mils (cmil) for a 6 AWG wire is 41,740 cmil.
For three 6 AWG wires:
- Total area = 3 × 41,740 cmil = 125,220 cmil
Step 2: Determine the conduit size
The NEC provides conduit size based on cmil. For example, a 1/2″ flexible conduit typically has an internal diameter of around 0.624 inches, which accommodates up to 100,000 cmil of conductor area.
Since 125,220 cmil exceeds the 100,000 cmil for 1/2″ flexible conduit, you would need a 3/4″ flexible conduit. A 3/4″ flexible conduit is usually rated to handle up to approximately 200,000 cmil.
Conclusion
The minimum inside diameter of flexible conduit required to house three 6 AWG wires is 3/4 inch. Always ensure that you check your local code and specific conduit manufacturer’s guidelines to confirm the appropriate size.
