Frequently Asked Questions
How are these labor hours calculated?
This tool generates rough estimates based on typical industry heuristics for conduit installation (EMT/PVC) and wire pulling (THHN), rather than strict code tables. It factors in baseline times for rough-in, wire pulling, device make-up, and panel work.
Why is the estimate given as a wide range?
Labor is inherently variable. While materials can be calculated precisely, labor efficiency swings wildly based on contractor experience, site access, open vs. finished walls, and local conditions. A wide range is the most honest way to approximate labor without visiting the site.
