01 / What we do

The power side of
your machines.

We are the electrician. We bring the power to the machine and keep it right.

01

Machine Hookups

Haas and Doosan mills and lathes, other CNC mills and lathes, Swiss machines, presses, grinders and saws, wired to the spec sheet.

02

480V & 208V Three-Phase

Three-phase power and distribution to the machine: feeders and disconnects sized to the spec sheet.

03

208 vs 480 Mismatch

Machine and shop on different voltages? Buck-boost or step-up/step-down transformers, or a phase converter if the shop only has single-phase.

04

Shop Needs More Power

Service, panel and transformer upgrades when the new machine is more than the shop can feed, including large industrial services.

05

Rest of the Floor

Circuits and disconnects for the welders, compressors, chillers and dust collectors that run next to the machines.

06

New & Expanding Shops

Moving into a new space or adding a bay? We fit out new and expanding shops and hook the machines up to their spec sheets.

Electrical only. We handle the power side: feeders, disconnects, connections and voltage. Mechanical, control and software service on the machine stays with your dealer or machine tech, and your rigger sets the machine. We coordinate with both.

01

Preventive Electrical Checks

Disconnects, feeders, connections and voltage at the machines, checked under a maintenance program.

02

06 / Questions

Shop floor
questions.

Can the power be ready before the machine arrives?

That's the goal. Send the delivery date with the spec sheet and we'll work with your dealer and rigger so the power is ready on install day.

Do you hook up Haas and Doosan machines?

Yes. We wire Haas and Doosan mills and lathes, and other CNC brands, to the machine's spec sheet: feeder, disconnect, connection and the right voltage. We're the electrician, not a dealer, and we're not affiliated with Haas Automation or Doosan (DN Solutions). Mechanical, control and software service stays with your dealer or machine tech.

The machine is 480V and our shop is 208V. Now what?

That's a voltage mismatch. Depending on the machine, we fix it with buck-boost or step-up/step-down transformers, or a phase converter if the shop only has single-phase.

Do you repair the machine itself?

No. We do the electrical side: power, feeders, disconnects, connections and voltage. Mechanical, control and software service stays with your dealer or machine tech.

Can you work around production?

Off-hours work is available to avoid downtime. Put your shift schedule in the timeline field, or tell us when you call.

How fast do we get a number?

For straightforward scopes, we send back a written bid within 2 business days. Attach the spec sheet and photos so the scope is clear.

Who pulls the permit and deals with the inspector?

We do. Every job is permitted in our name, done by licensed electricians on our crew, inspected and closed out properly.

We have more than one shop. Can you cover all of them?

We run multi-site maintenance programs. Tell us where the sites are and we'll confirm coverage before you commit.

Can we get references?

References from industrial customers are available on request.

CNC machine on
the way?

Send the spec sheet, where it's going and the delivery date. We walk the shop, give you a written quote and work with your dealer and rigger so the power is ready on install day. Or call (973) 662-4333.
