Branch Circuit Wiring Takeoff | Shortcuts for Electrical Estimators

In this electrical estimating tutorial, you’ll learn useful shortcuts that can cut your branch circuit estimating time by as much as 25%.

00:00 - Introductions
00:33 - What is a branch circuit?
01:28 - What makes up a branch circuit?
01:47 - Old school branch circuit takeoff methods
02:38 - Branch circuit takeoff shortcut
02:53 - How to determine average length
04:11 - Final adjustments
05:51 - Sample branch circuit takeoff in EBM
08:54 - Old school home run takeoff methods
09:19 - Home run takeoff shortcuts
09:49 - How to determine # of home runs
10:09 - How to determine the length of home runs
11:37 – Sample home run takeoff in EBM
13:52 - Q&A | Is there a way to label branch circuits and home runs on takeoff so its easier to identify on the audit trail?
15:29 - What type of jobs can I these formulas be used for? (i.e. commercial, industrial, residential)?
16:42 - Does the location of the electrical room affect the dimension formula?
18:07 - What if there are multiple electrical rooms?
18:24 - Are points the beginning and end of a branch circuit run or just one end?
19:54 - In EBM, can switches and lighting be handled the same way as receptacles?
20:45 - Can the adjustment for room height be done as an adjustment at the takeoff level?
21:39 - How do in include dimming wires for 0-10v lighting systems

Formulas Used:
Avg length = √(Square footage /# of points)

of home runs = # of 20 amp circuits for a given panel / 3

Avg home run length = longest dimension / 2 x 10
