Essential Electrical Requirements for Custom Automation Builds: What Design-Build Shops Should Know Before Installation Day

Automation builders and machine OEMs spend months designing systems, building panels, and programming equipment. But one overlooked area consistently causes delays:

Electrical preparation at the customer’s facility.

Before automation equipment arrives onsite, several electrical conditions must be correct—or installation day becomes a disaster of surprises, delays, and unplanned costs.

Here’s what design-build automation shops need to know to keep projects running smoothly.

1. Verify Voltage, Amperage & Phase Long Before Delivery

One of the most common causes of installation delays is discovering that the facility’s power does not match the requirements of the machine.

Checklist:

  • Correct voltage (120V, 208V, 240V, 480V, 600V)
  • Correct phase (single-phase vs. 3-phase)
  • Sufficient amperage capacity
  • Availability of a dedicated circuit
  • Proper grounding location

A mismatch means delays, extra costs, and unhappy customers.

Your equipment should never arrive without these verified.

2. Disconnect Switches Must Be Properly Sized & Located

Ontario’s ESA requires that industrial machines have:

  • A dedicated, lockable disconnect
  • Within sight of the machine
  • Properly labeled
  • Sized correctly for the maximum machine load

Missing or undersized disconnects cause:

  • Inspection failures
  • Commissioning delays
  • Liability risks

A competent industrial electrician ensures correct installation from the start.

3. Plan for Clean Conduit Routing & Cable Management

Poor conduit paths make installation messy and maintenance difficult.

Ideal routing should:

  • Separate high-voltage and low-voltage paths
  • Avoid tight bends or pinch points
  • Keep cable trays organized
  • Allow expansion for future upgrades
  • Maintain correct entry points into control panels

Clean routing = faster installation and easier servicing later.

4. VFD, Servo, and Motor Requirements Must Be Anticipated

Automation equipment often includes:

  • VFDs
  • Servo drives
  • Stepper drives
  • High-inrush motors
  • Position sensors

Each has specific electrical requirements to avoid noise and interference:

  • Shielded cable runs
  • Proper grounding and bonding
  • Correct conductor sizing
  • Separation from analog signals
  • Dedicated circuits for large loads

Ignoring these creates headaches for both electricians and integrators.

5. Pre-Installation Site Visits Prevent Costly Delays

A simple 30–60 minute walkthrough by a qualified industrial electrician eliminates most site-day issues.

During a site visit, we check:

  • Service capacity
  • Panel space
  • Feeder routing
  • Disconnect requirements
  • Cable paths
  • Grounding points
  • ESA compliance requirements

Design-build firms who use pre-install visits deliver smoother installations and happier customers.
