Whether you’re looking for a portable generator connection or a fully automated standby system, we install safe, reliable backup power solutions to keep your property running during outages.
Power loss is more than an inconvenience. It can interrupt your business, compromise your safety, and lead to costly damage to appliances, refrigerated goods, or technology. We help you prepare with generator systems that match your electrical needs, lifestyle, and budget — all installed to code by a licensed, local electrician.
Since 2020, GR Electric LLC has delivered clean, guaranteed installations backed by straightforward communication and professional service.
Why Install a Generator?
Severe weather events, aging utility infrastructure, and unexpected grid failures are all becoming more common across Connecticut and the northeast. A generator provides peace of mind by automatically or manually supplying power when the utility service fails.
Common reasons property owners install generators include:
- Frequent power outages or brownouts
- Remote or rural properties with unreliable grid access
- Essential medical or mobility equipment in the home
- Refrigeration and sump pump needs during outages
- Maintaining business operations and technology uptime
- Preventing frozen pipes or HVAC shutdown during winter outages
- Protecting food storage and sensitive electronics
We install both manual and automatic generator systems and ensure each is sized properly for your needs.
Portable Generator Installation and Hookups
Portable generators are a flexible and affordable solution for backup power. When combined with a professionally installed transfer switch, a portable generator can safely power essential circuits without the risk of backfeeding or overloading.
Our portable generator services include:
- Installation of manual transfer switches
- Generator inlet boxes (outdoor connections)
- Circuit selection and load planning
- Cord and connector configuration
- Labeling and instruction for safe use
We’ll help you select which circuits to power — such as refrigeration, lighting, outlets, sump pumps, or heating — and make sure your system is safe to operate when you need it most.
Standby Generator Installation
For property owners who want automatic, whole-house protection during outages, standby generators offer the highest level of performance and convenience. These systems are permanently installed outside your home and connect directly to your electrical panel and fuel source.
GR Electric LLC installs standby generator systems from top manufacturers, including units powered by natural gas or propane.
Our standby generator services include:
- Sizing the generator based on your home or business load
- Coordinating with plumbers or gas providers as needed
- Installing automatic transfer switches (ATS)
- Integrating the generator with your electrical panel
- Setting up load management for large appliances
- Final testing, labeling, and walkthrough
Once installed, a standby generator automatically detects outages and begins supplying power in seconds — even if you’re not home.
Generator Systems for Businesses
Commercial properties have different demands and higher stakes during outages.
We install backup power solutions for:
- Small offices
- Retail spaces
- Medical clinics and labs
- Restaurants and food service
- Property management buildings
- Warehouses and light industrial spaces
We’ll help you determine which equipment needs power during an outage, such as security systems, computers, refrigeration, or lighting. Then we’ll install a safe, efficient generator system that meets local codes and utility requirements.
Generator Transfer Switch Installation
A key part of any generator system is the transfer switch. This device allows safe switching between utility and generator power.
We install:
- Manual transfer switches for portable generators
- Automatic transfer switches for standby systems
- Load shedding modules to prioritize circuits
- Interlock kits where applicable
All installations are completed according to National Electrical Code (NEC) requirements and inspected for safety.
Maintenance and Generator Safety
Even the best generator can fail if it’s not maintained properly. We provide recommendations for routine generator care and partner with local HVAC and generator techs when service is needed beyond the electrical scope.
Tips for generator safety:
- Never connect a generator to your panel without a transfer switch
- Keep portable generators outdoors and away from windows
- Use heavy-duty cords rated for generator use
- Test your system before storms or expected outages
- Schedule professional service if you detect irregular operation
We are happy to revisit any system we’ve installed if you ever experience problems or want to expand your coverage.

Choosing the Right Generator for Your Needs
We offer guidance at every step of the selection process. Key factors include:
- Property size and square footage
- Number of circuits or appliances to be backed up
- Desired runtime
- Fuel source availability (gas, propane, diesel)
- Manual vs. automatic transfer preference
- Budget and maintenance considerations
We also offer generator-ready panel upgrades for properties that may install a standby system later.
Frequently Asked Question
Do I need a permit for generator installation?
Yes. All generator systems that connect to your home’s wiring require permits and inspection. We handle this process for you.
Can I run my whole house on a portable generator?
Most portable generators are designed for essential circuits only. Whole-house coverage typically requires a larger standby generator.
How long does a standby generator last?
With regular maintenance, most standby generators last 10 to 20 years.
What size generator do I need?
That depends on what you want to power during an outage. We’ll calculate your load and recommend a properly sized unit.
Do you install generator interlock kits?
Yes, where permitted by code. Interlock kits are a cost-effective alternative to transfer switches for some portable setups.
