How do you estimate panel wiring labor for switchgear?

Multiply the terminations or wiring hours by your loaded labor rate, apply a productivity factor for real shop efficiency, then add fixed setup and test cost. With 100 units at $45, an 80% factor, and $250 setup, the total is $3,850.

What is the per-panel wiring cost in the example?

Dividing $3,850 by 100 units gives $38.50 per unit — the wiring labor loaded onto each panel or termination in the run.

Why apply a productivity factor to panel wiring?

Ideal wiring times assume no interruptions, but real work includes re-routing, waiting on drawings, and dressing. An 80% factor here means 80% of nominal time is productive, giving $3,600 of captured labor before setup.

What is included in the fixed panel setup and test cost?

One-time effort per panel that does not scale with termination count: fixturing the enclosure, point-to-point continuity checks, and final QA. In the example that is $250.

How much does control wiring cost per termination in a panel?

It varies widely by wire gauge and access, but a blended figure of $2-5 per control termination is common. This calculator uses a single blended rate, so split power and control if your panel mixes both heavily.

How do I reduce per-panel wiring cost on a repeat order?

Spread the fixed setup and test cost across more identical panels and improve the productivity factor with pre-cut harnesses and good drawings. On 10 identical panels the $250 setup drops to $25 each.

Switchgear, Panelboards & Electrical Distribution calculator

Panel Wiring Labor Calculator

Panel Wiring Labor estimates the cost of point-to-point wiring a switchgear lineup or panelboard — landing conductors, terminating control wiring, and dressing the panel to the schematic. In a UL 508A or switchgear shop, wiring labor is where estimates go wrong most often, because a panel with hundreds of terminations hides a lot of hours behind a deceptively simple bill of materials. Estimators and panel-shop supervisors use this figure to price a build and to see the true per-panel cost when a job repeats the same enclosure. It separates raw wiring hours from a realistic productivity factor so the number reflects the shop floor, not the ideal.

What this calculator does

Panel Wiring Labor estimates the cost of point-to-point wiring a switchgear lineup or panelboard — landing conductors, terminating control wiring, and dressing the panel to the schematic.
Use it when panel wiring labor in switchgear, panelboards and electrical distribution is being put through a switchgear, panelboards and electrical distribution weighted-cost review.
It computes total panel wiring labor cost from the number of terminations or wiring hours times a loaded rate, scaled by a productivity factor, plus fixed setup and test cost, and returns a per-panel figure.

Formula used

Panel Wiring Labor cost = quantity × rate × capture factor + fixed cost
Per-unit panel wiring labor = total cost ÷ quantity

Inputs explained

Terminations or wiring hours in the panel:
Loaded panel-wiring labor rate:
Productive wiring time factor:
Fixed panel setup and test cost:

How to use the result

Use it when quoting a switchgear or panelboard build, or when reviewing why a completed panel's wiring hours ran over the estimate.
It assumes a single blended wiring rate; it does not separate power-cable landings from fine control wiring, which carry very different times per termination, so mixed panels need a weighted rate.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
On-highway diesel averages $4.58 per gallon this week (EIA), trending down over recent periods. Truck tonnage is up 3.4% year over year (ATA via FRED).
The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
