Generator Shop Cordova TN Whole House Standby Generator Installation

Benchmark Electric, LLC is a Cordova-based Generator Shop specializing in turnkey standby generator installations. In addition, Benchmark is an authorized dealer for each of the top-three U.S. manufacturers of whole house generators, including:

Standby generator installations are handled exclusively by Benchmark Electric's factory trained professional technicians. Outside electrical contractors are never used.

Benchmark Electric only uses outside contractors when the work required is outside of their expertise (e.g., plumbing gas lines, concrete work, crane operators, etc.).

Most standby generator installations require a licensed electrician and plumber.

Whole House Generators

Whole house generators are connected to every circuit in the house and are sized to keep you comfortable throughout your home during summer and winter power outages. 

To accomplish connecting the generator to all house circuits, an automatic transfer switch (ATS) is connected to each main breaker panel. Homes with two or more main breaker panels will require an ATS for each panel. 

Now that the transfer switches are connected to each main breaker panel, the chosen standby generator must be able to maintain whole house electrical loads with all A/Cs starting and running along with other house loads also "on". Proper generator sizing is critical for whole house generators.

The big energy-consumers in most homes include:

  • Air Conditioners
  • Electric Heat
  • Electric Ovens
  • Clothes Dryers
  • Electric Hot Water Heaters

Consult a generator professional from Benchmark Electric to properly size a whole house generator for your home.


Partial House Backup Generators

Many homeowners are interested in covering "just the essentials". Enough to stay comfortable during an outage.

Here are a few of the more common essentials the pros at Benchmark Electric can connect to a home backup generator:

  • Fish Aquariums ← a popular request!
  • Refrigerator(s)
  • Freezer(s)
  • Microwave
  • Coffee Pot
  • Well Pump ← Important for having running water
  • Sump Pump ← Critical in preventing flooding
  • Home Health Care Medical Equipment
  • Gate Operator
  • Garage Door Opener
  • Gas Furnace Fan Blower Motors
  • Run 1-2 A/Cs (of 4+ A/C System)
  • Security System
  • TV / Cable / Satellite
  • Internet
  • 2-3 or more light circuits
  • and a host of unique circuits deemed "essential"

A 10-13kW should handle the other listed electrical loads above, excluding A/Cs. Step up to the Cummins RS20A for 20/18kW performance including the ability to start and run up to a 5-ton central air conditioning compressor.

Talk to a generator professional at Benchmark Electric for more information on partial house standby generators.

Portable Generators

Any portable generator can be safely connected to your house electrical panel without back-feeding over utility lines. So, don't worry about running extension cords in and out of doors and windows.

Benchmark Electric can connect your portable generator or supply you with a generator in sizes up to 17,500 watts. These higher wattage portables can power lights, TVs, laptops, refrigerators, freezers, window air conditioners and some 2-stage, high-efficiency central air conditioning compressors.

Benchmark Electric will supply you with a generator cord of any desired length. Simply connect one end to the generator and the other end to the outdoor receptacle installed by Benchmark Electric's expert technician.

Why Are We Seeing So Many Power Outages?

Over 50 million Americans lost power for more than a day in 2003. The grid-failure impacted the northeast USA from Ohio to New York and a portion of Canada.

An already weak power grid grows weaker each year due to a growing population, new construction, and more frequent extreme weather.

According to an article posted in Inside Energy, the number of power outages doubles every 5-years and has been doing so for over two decades. That means there has been an 8-fold increase in power outages in the past 20-years, underscoring the need for backup generators for many homes and businesses.

Generator Service

Routine Generator Service

  • Annual Generator Service

  • Generator Service - All Major Manufacturers

  • Generac Generator Service

  • Kohler Generator Service

  • Cummins Generator Service


Just like your car, a home standby generator requires periodic routine generator service. Manufacturers recommend major service at least annually. The routine typically includes an oil change, new oil and air filters, a new set of spark plugs.

Annual Generator Service

The annual generator service routine typically includes a fresh oil change, new oil filter and air filter, and new spark plugs. The service is complete after a 1-hour generator run test under house load.

Benchmark Electric sends its staff of generator technicians to factory training and recurrent training. Benchmark's generator technicians have attended factory and recurrent training at Cummins, Kohler, and Generac. These technicians have an uncanny ability to troubleshoot problems with standby generators in short order.

Benchmark Electric's technicians are well schooled in generator installation, service, and repair from a variety of manufacturers.

What To Do After Running Your Generator for Days following a Long Outage

It happens. Maybe it's a straight-line wind storm like Hurricane Elvis in July 2003. The Mid-South area is also prone to winter ice storms and ice storms almost guarantee long-term outages lasting several days.

Your home standby generator is programmed and optimized to run 24/7 or until utility power is restored.

Benchmark's generator professionals offer the following tips on keeping your generator properly serviced during a long-term outage and following the outage.

During a long-term outage, any home standby generator is designed to perform for days. Any air-cooled generator or liquid-cooled generator running at 3600 RPM should be shut down after 4-5 days to check the oil level. If the generator previously ran for, say, a couple of days during a previous outage, consider checking the oil level after running the generator 2-days.

Keep handy a quart of oil which matches the oil grade for your standby generator. If you don't know the oil grade, check the owners manual. Your generator may need additional oil after having run continuously for 4-5 days.

Important: Secure the oil fill cap and dipstick tightly, then set the generator on "Auto" for restarting.

Generator manufacturers recommend major service on any home standby generator following 100-hours of operation. If your generator runs continuously during a 4-5 day outage, the engine runtime will have exceeded 100-hours.

So, if your annual generator service isn't due for another 6-months, all manufacturers agree you should move up the major service routine immediately following an extended power outage.

It's truly unfortunate to find yourself without utility or generator power due to a dead battery, bad battery charger, or any other issue requiring generator repairs.

The best way to avoid the above situation is to have a generator monitoring device installed.

Generator Monitoring

Generator monitoring provides immediate notifications to homeowners when the generator starts, stops or issues a maintenance alert.

Cummins has a free SmartPhone App for monitoring its air-cooled line of standby generators. Free App + Free Monitoring!


Most manufacturers offer a local wired or wireless remote monitor. A "Green" LED light indicates all is well with the generator. A "Yellow or Red" LED indicates a problem. Some systems include a Text Display Message which provides a clue to the problem.

Other monitoring devices use Cellular or an Internet connection to send Email or Text Alerts when the generator starts, stops or has a maintenance alert.

Generator Shop Cordova TN Generator Repairs

Generac's MobileLink Remote Monitoring features cellular remote monitoring to Generac servers. MobileLink can be programmed to send email or text message alerts. The first 12-months of monitoring is free. Thereafter, monthly monitoring fees range from $10-$12.

Generator monitoring for late-model Kohler generators features online monitoring programmed to send email notifications or text messages. Called Kohler OnCue+, a connection is made from the generator to your wireless router.

Kohler OnCue+ is available for less than $400.00, includes free updates, and requires no ongoing monitoring fees. Simply supply an Internet connection. Access the software from any PC, laptop, tablet, or smartphone.


The Kohler OnCuePlus remote monitoring can be viewed on any laptop, tablet, or smartphone

If your home standby generator is not equipped for generator monitor, call Benchmark Electric to find out if there is a monitoring device available for your home standby generator.
