Home and Commercial Generators

Home Generators

Is your family prepared for emergencies resulting in a loss of power to your home? Without a home generator, you may be left in the dark.

What can a home generator do for me?

In the event of a power outage, home generators allow you to more easily meet basic life requirements until power is restored. They are useful in maintaining the operation of refrigerators, freezers, sump pumps, furnaces, stoves, lights, fans, yard equipment, and more, in the event of both short and longstanding power outages. Working much like the engine in your automobile, home generators create mechanical energy by converting fuel (gasoline, diesel, or natural gas) into electrical power with the help of a heavy-duty recharging battery.

Home generators are handy in a variety of situations:

  • Blackouts:  extremes in temperature and other times when there simply isn’t enough energy to meet demand.
  • Inclement weather: lightning, hurricanes, tornadoes, snowstorms and heavy wind.
  • Damage from animals:  second only to severe weather as a leading cause of power loss.
  • Natural disasters:  earthquakes, floods and fires.
  • Auto accidents:  interruptions in service resulting from unexpectedly and irrevocably damaged electrical equipment.

Types of Home Generators

Portable home generators power a few basic essentials in your home until power is restored. They must be manually started and connected to necessary appliances. Portable models cost less than standby models, and operate fewer appliances. They also come with the added danger of carbon monoxide risks when operated in improper locations.

Stationary or Standby
Typically natural gas or propane powered stationary generators cost more than portable models, and can manage all or most of your home’s electrical needs when power goes out. Used in conjunction with automatic transfer switches, they turn on automatically when power goes out in order to prevent an interruption in service.

The Right Size is Essential

It is important to properly calculate the wattage on essential items you wish to run with your generator simultaneously to determine the right capacity generator to meet your needs. Be certain to discuss electrical essentials with a Job Electrical Works professional in order to prevent undersized generators and overloading at startup.

You have the power, and you can keep it on with the addition of a home generator. Contact a professional at Job Electrical Works today for a free estimate and to learn more about finding the perfect generator solution for your home’s electrical needs.

Commercial Power Generators


Portable generators may be wired into a subpanel by an electrician or simply plugged into appliances using extension cords. They power only chosen essentials such as lights, refrigerators and some computers. They are a simple and inexpensive backup power option, but must be started and maintained. They offer a limited supply of electricity, providing enough power for two to four outlets or a few specific circuits when wired in. These generators must be located at least 10 feet away from your business, away from doors and windows, and in a completely open area (not even carports or awnings are safe) to avoid carbon monoxide poisoning.

Standby / Plant

Standby generators start automatically during power outages, preventing interruptions in electrical service. They are powered by natural gas or propane, are quieter than portable models, and have the ability to power everything in your business. They come at a higher price and also require the professional installation of a transfer switch, a subpanel, and the power generator itself.

Potential Problems

  • Battery failure: This is the single most common cause for power generator service. Battery failure may be the result of sulfate buildup on terminals, shorts, open cells, a tripped charger breaker, charger failure, or simply due to loose or dirty connections.
  • Low coolant: External and internal leaks, clogged radiators, and more can cause a power generator to run hot and shutdown.
  • Faulty block heater: Because they run so frequently, block heaters often become faulty resulting in a low coolant temp alarm.
  • Wet stacking: Excessive no-load run time can result in an over-fueled engine that becomes damaged due to the accumulation of carbon particles, unburned fuel, oil, condensed water, and acids in the exhaust.
  • Controls not in “auto”: This simply means the power generator was not shut off and may not be the main control switch. This can be due to human error, open breakers, alarms or switchgear not properly reset, emergency shutdown, and more.
  • Air in the fuel system: This can prevent injectors from firing and is typically due to generators that are not run on a regular basis. It can be prevented with weekly inspections.
  • Out of fuel: Generators will automatically shut down when fuel depletion is imminent to prevent the fuel system from drawing in air.
  • Breaker trip: If no one has accidentally pushed the emergency shut off, check the status of the automatic transfer switch (ATS). Never try to manually operate this switch if you do not know how to do so, as it could result in severe injury or death.

Warning! Never plug your generator into a wall outlet. This is also known as backfeeding. If you do this without throwing the main breaker to isolate your business from the grid, you could send power back on into the grid, potentially injuring or killing utility repairmen.

Professional Generator Installation

A professional can determine the right size generator for your needs.
Do you know how to properly calculate wattage so that your system isn’t overloaded at startup? This varies depending on the equipment you need to power and the manufacturer of your generator. Our professionals have the skills necessary to calculate power needs for a smooth operation.

Professional installation ensures safety.

A professional electrician can safely set up wiring, plugging your generator into the transfer switch and wiring it directly to your business’s service panel. This disconnects you properly from the grid and ensures the safe delivery of power only to designated circuits, preventing the overloading of you generator, backfeeding, fire, and other safety issues. Proper positioning and installation of your portable generator is also essential in preventing carbon monoxide poisoning.

Job Electrical Works arranges for the inspection of your newly installed power generator.  This ensures all local codes and regulations are met.
