Commercial kitchens rely on properly installed electrical systems to keep equipment running safely and efficiently. In this project, Smiley Electric completed new circuit installations for restaurant equipment across two locations — including a second site in Fairview, Oregon, and a deli location in Portland.
This vlog highlights how professional electrical planning, conduit layout, and panel coordination are essential when powering high-demand kitchen equipment like fryers and food warming centers.
Project Overview
The scope of work included:
- Installing two new dedicated circuits
- Running 1-inch and ¾-inch EMT conduit
- Connecting equipment to three-phase power
- Installing required disconnects
- Reworking existing wiring to proper gauge sizes
Each piece of equipment had specific electrical requirements that dictated conductor size, conduit routing, and overcurrent protection.
Single-Phase vs. Three-Phase Panel Coordination
One challenge on this project was working with both single-phase and three-phase panels.
- The ¾-inch EMT circuit was landed in a single-phase panel
- The 1-inch EMT circuit carried larger-gauge conductors and was landed in a three-phase panel
Proper panel selection ensured:
- Correct voltage and capacity
- Safe conductor sizing
Long-term reliability for commercial equipment
Conduit Routing & Code Compliance
Running conduit in commercial spaces requires strict adherence to electrical code.
Key Considerations
- NEC limits conduit runs to no more than 360 degrees of bends
- Junction boxes were installed to:
- Stay code-compliant
- Provide pulling points
- Allow future service access
- Stay code-compliant
Conduit runs were carefully routed along back walls, through LBs, and down into disconnects to maintain a clean, professional installation.
Dedicated Circuits for Fryers & Warming Equipment
At the Portland deli location, Smiley Electric installed power for:
- A commercial fryer
- A food warming center
Why Multiple Circuits Were Required
The fryer contained two separate bays, each requiring its own dedicated circuit to handle the electrical load safely.
Additional work included:
- Replacing undersized existing wiring with correct-gauge conductors
- Installing new junction boxes for proper splicing
- Labeling circuits clearly inside the panel
Disconnects & Equipment Safety
Due to distance from the panels, disconnect switches were installed near the equipment.
Disconnects allow:
- Safe servicing and maintenance
- Code compliance for commercial installations
- Quick shutoff in emergency situations
From the disconnects, SO cord and hardwired connections were routed cleanly to the equipment’s designated locations.
Final Testing & Walkthrough
At project completion:
- All conduits were strapped and secured
- Breakers were installed and labeled
- Fryer and food warmer were powered on and tested
- Equipment operated normally with no faults
Some equipment was converted from hardwired connections to cord-and-plug setups for easier servicing, per customer request.
Why Professional Commercial Electrical Work Matters
Commercial kitchen equipment places heavy demands on electrical systems. Improper wiring can lead to:
- Equipment failure
- Fire hazards
- Failed inspections
- Business downtime
Professional installation ensures safety, reliability, and compliance from day one.
