Use this junction box sizing calculator to determine the recommended dimensions of a junction box depending on the number of straight and angle pulls entering it and meet the National Electrical Code®. A junction box, also known as an electrical box is an enclosed housing space to accommodate electrical connections. But there is a limit on how many wires in a junction box are acceptable. It depends on two key factors.
Be sure to use the correct size wire nut: if the nut is too small, the wires won’t fit, and if it’s too big, the wires could loosen and fall out. Wire nuts are color-coded for AWG and capacity, both of which are also listed on their . For example, a box that contains three to six conductors requires a minimum volume of 18 cubic inches, while a box that contains seven or eight conductors requires a minimum volume of 20 cubic inches. Section 370-29 . How to Size a Junction Box (18 AWG to 6 AWG) If the conductors in your junction box are of size 18 AWG through 6 AWG, you’ll use the tables in NEC 314.16 to determine the minimum volume of your junction box. For your . Correct fill capacity: The junction box should be large enough to contain the wires. Many DIYers choose the largest box practical for the application. To stay within code-approved limits, though, consult a fill capacity .
