Commercial Backup Generators

Keep Your Business Powered — No Matter What Happens

When the lights go out, your business can’t afford to stop. Power outages cost time, revenue, and safety — especially for retail stores, restaurants, offices, and multi-tenant buildings that depend on consistent power for daily operations.

At The Wire Nuts, we design, install, and maintain commercial backup generator systems that keep your business running during outages, storms, or grid interruptions. Our solutions are tailored to your building’s power needs, ensuring seamless operation when it matters most.

Why Commercial Facilities Need Backup Power

Even a short outage can cause major disruption — from spoiled inventory and halted transactions to safety and security risks.

Backup generators provide:

• Continuous power to critical systems during blackouts

• Lighting and security system uptime for staff and customers

• Business continuity for computers, registers, and HVAC

• Automatic transfer switches (ATS) that restore power within seconds

• Protection against downtime losses and data interruptions

We’ll help you select the right generator capacity to keep essential systems operating without overpaying for unnecessary load.

Generator Installation & Integration

We handle the entire installation process, from system design to commissioning and inspection.
Our licensed electricians ensure your generator integrates seamlessly with your existing electrical service.

Our generator installation services include:

• Site evaluation and load analysis

• Sizing and equipment selection (natural gas, diesel, or propane)

• Concrete pad placement and mounting

• Automatic transfer switch (ATS) installation

• Electrical integration with panels and subpanels

• System testing and start-up verification

We coordinate with your utility provider and local inspector to ensure every installation is safe, compliant, and ready for emergencies.

Maintenance & Service Plans

A generator is only reliable if it’s maintained properly.
We provide scheduled generator maintenance programs to keep your system ready at all times.

Maintenance includes:

• Load bank testing and performance verification
