You can use the chart below to calculate the required box size. Add up the numbers for the correspond- ing components in the box to find how many cubic inches you’ll need. In most cases, I skip the math and just buy the .
The National Electrical Code (NEC) provides guidelines for box sizing based on the number and size of wires you're working with. The NEC specifies the minimum volume of the box in cubic inches (cu. in.) that you . According to the 2020 NEC®, our box should have a size of at least eight times the largest conduit when considering straight pulls.
