CodeBuddy – Field Compliance

CodeBuddy brings real electrical code calculations into your conversation. Ask the way you would on site ("How many 12 AWG fit in a 4x4 box with two devices?", "Is 3% voltage drop OK on a 150 ft run?") and CodeBuddy opens the right calculator with the values it understood.

Nothing is calculated until you confirm. The card shows what the AI filled in, marked as an AI guess, and asks only for what's missing, such as the code edition. Tap Confirm and calculate and you get a cited result: the numbers against the allowance, the worked math, the section references and the edition the result is based on.

Twelve calculators for the US and Canada: box fill (including how many fit), conduit fill, voltage drop, wire ampacity with temperature and conductor-count correction, transformer protection and conductor sizing, and residential service load.

Results are deterministic: the same inputs always give the same answer, computed by CodeBuddy's tested calculation engines, not generated text.

From any result you can continue in CodeBuddy: save the calculation to a job, ask about your own jurisdiction's adopted edition and amendments, or pre-inspect the box with your phone's camera.

Who it's for: electricians, apprentices, inspectors and contractors. Limitations: it calculates; it doesn't quote code text or answer general code questions. Reference only: results are based on the stated code edition's values; verify against the code edition and amendments adopted by your authority having jurisdiction. Not engineering advice.
