Generator Transfer Switch Installation in Denver, CO : Jim Needham Heating, Cooling, Plumbing, Drain & Electrical

Owning a generator is a smart step—but without the right switch, it won’t perform the way it should. A transfer switch ensures that power transitions smoothly and safely during an outage, keeping your essential circuits running without the need for manual rewiring or risky workarounds. At Jim Needham Heating, Cooling, Plumbing, Drain & Electrical, we install code-compliant switches that make backup power automatic, reliable, and easy to manage.

These devices safeguard utility crews and prevent damage from power surges or backfeeding. Our Denver electricians install both automatic and manual switch systems with precision, tailoring the setup to your home’s layout and energy needs. You’ll be ready for outages with a solution that’s safe, seamless, and built to last. No service call fees, no shortcuts—just expert installation from a team that gets it right the first time.

Why Is a Transfer Switch So Important for Home Backup Power?

Connecting a backup system directly to your home without a transfer switch can be unsafe and, in many cases, illegal. These devices safely isolate your electrical circuits during an outage, allowing backup power to flow only where and when it’s needed. They also prevent energy from backfeeding into the grid, which can endanger utility workers and damage sensitive equipment.

Here’s what a professionally installed switch allows you to do:

Seamlessly switch between utility and generator power without rewiring

Protect sensitive electronics from power surges during transition

Eliminate the need for extension cords running through your home

Keep only essential circuits powered or control full-home coverage

Maintain code compliance and simplify future inspections

Installing the right switch isn’t just a smart upgrade—it’s a vital part of making your backup system functional and safe. Our team ensures every connection is solid, secure, and ready to activate when the power goes out.

What’s the difference between a manual and automatic transfer switch?

A manual switch requires someone to physically activate it during an outage, typically by flipping a lever or pressing a button to redirect power from the grid to your backup system. An automatic switch detects power loss instantly and transfers the electrical load without any user input. If you’re looking for seamless protection or often away from home, automatic is usually the better choice—but both options are safe and reliable when professionally installed.

Is it safe to use a generator without a transfer switch?

Running a system without the proper switch can be extremely risky. Without safe isolation, power can backfeed into the utility grid, creating hazards for repair crews and damaging electrical components inside your home. A transfer switch ensures that only one power source is active at a time, giving you a cleaner, safer, and code-compliant setup.

Can I choose which circuits are connected to the transfer switch?

Yes—our team will help you prioritize the circuits you want to remain active during an outage. Common choices include HVAC systems, refrigeration, lighting, sump pumps, and home office equipment. By focusing on what matters most, you’ll use your system more efficiently and avoid overwhelming your backup power supply.
