Engineering solution

Electrical Engineering & Control Panel Design

Geek Engineering provides electrical engineering and control panel design for machines, production lines and industrial systems: power distribution and motor circuits, schematics, panel layouts, I/O and cable schedules, and documentation packages reviewed against applicable NEC, NFPA 79 and UL 508A requirements per scope. Work is delivered from Rosemont, Illinois for Chicagoland plants and for qualified projects nationwide.

Why this solution exists

Electrical problems on machines are usually documentation problems first. Panels get modified for years without the schematics following, breakers and wire sizes drift from the original calculations, and the next upgrade starts with nobody certain what is actually installed. Good electrical engineering is as much about producing drawings that stay true as it is about the original design.

This engagement covers the electrical design scope end to end — from load calculations and component selection through schematics, panel general-arrangement drawings and the I/O documentation the controls work depends on. Because the same office does controls and software, the electrical package is designed around how the machine will actually be programmed and maintained, not thrown over a wall.

This is a strong fit when

  • OEMs and machine builders who need a complete, repeatable electrical design package
  • Plants adding equipment, upgrading drives or correcting years of undocumented panel changes
  • Integrators and panel shops that need overflow design capacity with clean deliverables
  • Projects where electrical, controls and software must be designed as one system

Scope

What the work includes

Design coverage

  • Power distribution, branch circuits, motor and drive circuits, and load calculations
  • Control panel design: layout, thermal and spacing review, component selection and BOM
  • Schematics and wiring diagrams in the format your shop and plant standardize on
  • I/O lists, cable and conduit schedules, and field device specifications
  • Short-circuit current rating documentation support and labeling guidance
  • As-built recovery: bringing drawings back into agreement with the installed system

Standards handling

  • Applicable NEC (NFPA 70), NFPA 79 and UL 508A construction requirements reviewed per project scope
  • The compliance path — who inspects, who lists, who signs — identified in writing before design starts
  • Design decisions documented with their code basis, so reviews do not restart the reasoning

Required inputs and deliverables

What we need from you

  • Machine or process description and the sequence of operation
  • Existing drawings, photos and nameplate data where equipment already exists
  • Site power characteristics and any plant electrical standards
  • Preferred component vendors or an existing panel standard, if any
  • The inspection and listing requirements your jurisdiction or customer imposes

What you receive

  • Complete schematic set with revision control
  • Panel general arrangement and layout drawings with the bill of materials
  • I/O list, cable schedule and device specifications ready for the controls scope
  • Load, breaker and wire sizing calculations as a reviewable document
  • A build-ready package a qualified panel shop can quote from without clarification rounds

Project process

How the engagement runs

  1. STEP 1

    Scope and standards review

    Agree what is being designed, which codes apply, and who holds listing and inspection responsibility.

  2. STEP 2

    Load and architecture design

    Size the power system, select the major components and fix the panel architecture.

  3. STEP 3

    Detailed design

    Produce schematics, layouts, I/O documentation and the bill of materials.

  4. STEP 4

    Design review

    Walk the package with your team and the building shop; close comments in writing.

  5. STEP 5

    Build and field support

    Answer shop questions during the build and update drawings to as-built after commissioning.

Three electrical engagements, and which one you need

Electrical Engineering & Panel Design: three electrical engagements, and which one you need
EngagementStart here whenWhat you receive
New designA machine, line or panel is being built and no design exists yetThe full calculation, schematic and panel package, build-ready
Design-and-build coordinationYou need the panel designed and the listed build managed to completionThe design package plus shop selection, build QA and delivery oversight
As-built recoveryThe installed system and its drawings have gone separate waysField-verified schematics and a documented change history

Risks and limitations we state up front

  • Undocumented existing installations can change the design basis mid-project; as-found verification is scoped first for brownfield work.
  • Component lead times shift; the design names acceptable alternates for long-lead items where they exist.
  • Jurisdictions differ on inspection and listing expectations — identifying that path early is part of the engagement, and skipping it is how projects fail inspection late.

What drives cost and schedule

We do not publish fixed prices: these are the factors that determine effort. A scoped proposal follows the technical fit review.

  • Panel count and I/O size
  • Brownfield documentation recovery versus clean new design
  • Drive, motion and safety circuit complexity
  • Plant standards that constrain component selection
  • Level of shop support and as-built updating requested

What this engagement is not

The boundaries are stated rather than discovered: no professional engineer stamping, no in-house listed panel fabrication, and no licensed installation trade work. Each of those is identified during the standards review and assigned to the appropriately qualified party, with our design package written so their job is clean.

Electrical Engineering & Panel Design: common questions

Is Geek Engineering a UL 508A listed panel shop?

No, and we say so plainly: we design to UL 508A construction requirements as reviewed for each project's scope, and when a listed panel is required, the build is placed with a qualified listed shop — yours or one we coordinate. Design and listing are different responsibilities, and pretending otherwise is how panels fail inspection.

Can you provide PE-stamped electrical drawings?

Professional engineer stamping is not a service we hold out; where a jurisdiction or contract requires a stamp, that need is identified during the standards review and the work is routed to an appropriately licensed engineer. What we deliver is the complete, reviewable design package that makes that review fast.

Can you fix drawings that no longer match the panel?

Yes — as-built recovery is a defined scope here, not a favor. The installed system is verified by inspection and photographs, the schematics are corrected to what is actually wired, and the delta gets documented so your team knows what changed and why it matters for the next modification.

Which areas do your electrical design services cover?

Design, calculations and documentation are produced in Rosemont and delivered to projects anywhere in the United States; panel reviews and field verification are most practical across Chicagoland and Illinois, and are scheduled as planned visits for sites further out. Installation itself is licensed trade work and is assigned accordingly.
