Backup Power That Starts When You Need It

Generator installation and service for homes and businesses in Leominster, Massachusetts.

Your home or business in Leominster loses power during winter storms, summer thunderstorms, and unexpected grid failures, and when the lights go out, heating systems stop, refrigeration fails, and daily routines or operations come to a halt. Whether you live in a residential neighborhood near the center of town or operate a business along Route 12, a properly installed generator restores power automatically when the utility supply drops. Advanced Electrical Contracting works with homeowners and business owners throughout Leominster to install and service generators that provide reliable backup power when outages occur.

The work includes selecting a generator sized to your electrical load, installing the unit with proper fuel connections and transfer switches, and integrating it with your existing electrical system so it activates automatically during outages. Licensed electricians handle all wiring, permitting, and code compliance, then test the system under load to confirm it delivers power to the circuits you need most. The team has worked with residential, commercial, and industrial clients in the area for 26 years and understands the seasonal weather patterns that make backup power essential.

How Generator Installation Works in Practice

When you schedule installation in Leominster, the electrician calculates your total electrical load by reviewing your panel, identifying which circuits you need to power during outages, and recommending a generator with adequate capacity. The team installs the generator on a concrete pad outside your building, connects it to your natural gas line or propane tank, and wires it to an automatic transfer switch that monitors utility power and starts the generator when an outage occurs.

After the installation is finished, your generator starts automatically within seconds of losing utility power, your essential circuits receive steady electricity, and your heating, refrigeration, or business equipment continues operating without interruption. The electrician tests the system by simulating an outage and verifying that the transfer switch and generator respond correctly.

All work is completed by fully licensed and insured electricians with extensive generator experience, and the veteran-owned team ensures safe integration with your existing electrical system. If your generator requires ongoing maintenance or repairs, the team provides service visits to test operation, change oil and filters, and address any issues before the next storm season.

Questions People Ask Before Installing a Generator

Homeowners and business owners in Leominster often want to know what size generator they need, how long installation takes, and whether the system requires regular maintenance, so here are answers to the most common questions.

What size generator do I need?
The electrician calculates your load by adding up the wattage of the circuits you want to power during an outage, then recommends a generator with enough capacity to handle that load plus a safety margin. Most homes in Leominster need generators between 10 and 22 kilowatts depending on heating systems and appliances.
How long does generator installation take?
A typical residential installation takes one to two days, including setting the generator pad, running fuel and electrical lines, installing the transfer switch, and testing the system. Commercial and industrial installations in Leominster may take longer depending on the size and complexity of the electrical system.
What happens when the power comes back on?
The automatic transfer switch senses when utility power is restored, switches your building back to grid power, and shuts down the generator after a brief cooldown period. You do not need to do anything manually for the transition to happen.
What type of fuel do generators use?
Most generators in Leominster run on natural gas from your existing utility line or propane from a tank installed near the unit. The electrician helps you choose the best fuel option based on availability and your backup power needs.
When should I schedule generator maintenance?
You should schedule maintenance at least once per year, ideally before winter storm season, to test the generator under load, change the oil and filters, and verify that the transfer switch operates correctly. Regular maintenance prevents failures during actual outages when you need the system most.
