Two Dedicated Machine Circuits in a Vancouver, WA Warehouse
We ran two dedicated circuits for shrink wrap machines in a Vancouver warehouse, a 60-amp and a 20-amp, each in conduit across the tilt-up concrete. We put a fused disconnect at the machine and pulled the permit.

Scope of Work
- Ran a 60-amp dedicated circuit to a shrink wrap machine
- Ran a 20-amp dedicated circuit to a second machine
- Ran both in conduit across the tilt-up concrete walls and structure
- Put a fused safety disconnect within sight of the machine
- Pulled the permit for the installation
Production machines don’t move to suit the panel. Two shrink wrap machines went into a warehouse in Vancouver, WA, and the circuits had to come to them: a 60-amp and a 20-amp, both run in conduit across a building made of tilt-up concrete and steel.
Why each machine gets its own circuit
Both machines got their own dedicated circuit. That’s the only way to feed production equipment:
- If one trips, only one machine stops. Put two wrappers on one circuit and one problem stops both.
- Motors pull hard when they start. The start-up surge from one machine on a shared circuit is what makes the other one fault out.
- You can troubleshoot. When a machine acts up, you want to shut off just its power and test it.
That last one pays for itself. An hour of downtime on a packing line costs more than the whole install.
Conduit on concrete walls
You can’t fish wire through a wall in a building like this. The walls are concrete, the roof is steel deck, and you see every foot of the run.
So a good job looks different:
- We plan the route knowing people will see it. Runs go square to the building, side by side where they share a path, and follow the structure.
- We hang it off the structure, where the building can hold it.
- We keep it high. Runs go above the dock doors and out of forklift reach, which is why the run in the photo sits up under the roof deck.
That’s most of the difference between real warehouse electrical work and house habits used in a big room.
The disconnect goes by the operator
We put a fused safety disconnect within sight of the machine.
Code requires it, and it’s what makes the machine safe to work on. Whoever’s clearing a jam or servicing the wrapper can shut off the power right where they’re standing and see that it’s off. A breaker in a panel across the building doesn’t do that.
Permitted
The work went in under permit. On commercial equipment circuits, that’s required, and it’s what the building owner and the insurance company will look for.

Real Reviews
What customers say about our commercial work
Anthony was awesome! Professional, courteous, efficient and friendly. He was careful to ensure accurate placement of a new outlet prior to starting work. He performed the work quickly, safely and cleaned up when he was done. I have worked with Newman Electric on multiple projects and I appreciate the quality of each of their team members that has served us. I will continue to refer them to friends, family and colleagues.
Newman Electric is top notch. We use them for our personal projects and have used them for 10+ remodeling projects for our business and they have always showed up on time and been honest with pricing. Ryan and his crew are professional and friendly! I highly recommend.
