Partners

Build with a manufacturer your projects can stand on

EPCs, electrical contractors, consulting and specifying engineers, and facility teams partner with Critical Power RPP for build-to-spec Remote Power Panels, a 4-week delivery you can schedule around, and a real engineer on every call.

Why partner with us

A domestic source you can put your name on

When you specify a panel, you are vouching for it — to the owner, to the inspector, and to the AHJ. We give you something solid to stand behind: Sentinel Series RPPs engineered and built in the USA, UL listed, BABA-compliant, and backed by an engineering team that picks up the phone.

We are a Siemens Approved OEM with multi-OEM component sourcing, so the breakers and gear inside the panel are an engineering decision, not whatever was on the shelf. The result is a clean submittal, a predictable date, and a build that matches the one-line you drew.

Build-to-spec — the panel fits the room and the load, not the catalog
4-week delivery on a date you can sequence the rest of the job around

Who we build for

One source, every seat at the table

From the engineer specifying the panel to the contractor installing it to the owner living with it.

⚙

EPCs & Integrators

A single domestic source for repeatable RPP packages across multi-site programs, with expedited options when a date moves.

🛠

Electrical Contractors

Clean, listed builds that pass inspection, ship on schedule, and install without surprises — with top and bottom cable entry to suit the room.

✎

Specifying Engineers

Talk to the engineer who will build it. Send a one-line and we tell you exactly what we would build and how it ships.

🏢

Facility Owners

Build-to-spec RPPs sized for the room and the future load — metered, seismic-tested, and supported for the life of the panel.

How it works

Send one line. We engineer it. We ship it.

No long RFQ cycles, no engineering by email tag. A short, technical path from drawing to delivery.

Step 1

Send your one-line

Share the one-line, the load schedule, and the room. An engineer reviews it directly — main breaker rating, branch positions, voltage, SCCR, and footprint.

Step 2

We engineer the build

We return a configured Sentinel Series submittal — SN-225, SN-400, or SN-600, with InSight BCMS, the SCCR you need, and the cable entry and mounting that fit the space.

Step 3

We build and ship

On approval, the panel is fabricated, assembled, and tested under one roof, then delivered in 4 weeks — listed, labeled, and ready to set.

InSight BCMS monitoring and engineering support

The support behind the panel

An engineer on the first call, not a ticket queue

Partnering with us means design, fabrication, and assembly never leave our roof — so intent never gets lost in a handoff, and the person who answers your question can actually change the build. That is what lets a non-standard panel still ship in 4 weeks.

We support you through the submittal, the inspection, and the install: stamped documentation for the AHJ, InSight BCMS commissioning, and a domestic supply chain that does not strand you when a schedule tightens.

What a partnership delivers

Built to spec, on a date, and easy to stand behind

⏱

4-Week Delivery

In stock now and a 4-week build-to-spec lead time — a real date you can sequence the rest of the project around.

✓

UL-Listed Construction

Listed, tested, and inspected before it ships — with 14 kAIC SCCR standard and 65 kAIC optional.

⚑

Made in the USA

Engineered and built domestically and BABA-compliant — qualifies federally funded work by default.

⚙

Built to Your Spec

Free-standing, wall-mounted, or back-to-back; top and bottom cable entry; voltage and branch count to match the one-line.
