As any New England resident knows, the weather in the Northeast brings risks of downed power lines due to snow fall, ice storms, hurricanes, lightning, and the infamous Nor’Easter.  Since these storms leave many in the dark without power for extended periods of time, it’s important to ask yourself the following questions:

  1. Have you taken inventory of the appliances and services in your home that would be shut down during a power outage?
  2. What are the consequences, if these appliances are rendered useless due to a power outage?

Generator General Info

How to choose a generator
Residential generators come in a broad range of sizes to meet the diverse needs of home owners. This page will help to explain how to choose a residential generator, pros and cons or generator options and how to prepare for your generator evaluation. Of course you can always feel free to just give us a call for a free consult.

Some of the things you will need to consider is…

  • The size of the system – how much of your stuff will you want to run during an outage
  • Portable vs Standby – Do you want to hook it up when the power goes out? Or do you want it to kick right on like nothing ever happened?
  • A gasoline, natural gas or propane generator. What will be your most affordable and efficient fuel choice.

How to prepare for your generator evaluation

We’ve put together these steps to help you prepare for an evaluation of a generator suitable to meet your needs:

  • Make a list of appliances/equipment you HAVE TO HAVE running during a power outage
  • Make a list of the NICE TO HAVE appliances.
  • Check the safety tags on your appliances, to put together your wattage requirements.

These choices are best reviewed together with a knowledgeable and reputable technician. RALCO, with its 25 years in business working with homeowners on their electrical needs, maintains a staff with the expertise to guide through all your choices.


What to expect

We’ll send one of our generator specialists to your home to conduct an assessment of your needs and to evaluate your site. You will have to take an active part in the evaluation process. We provide the options that fulfill our clients wishes.


Pros and Cons of generator options

Here are some guidelines to hlep you assess the pros and cons of generator options:

Option Pros Cons
Portable gasoline generator Lowest price. Short running time; needs gas tank refilled which may be a problem if you’re away from your home; usually lower power than stationary generators.
Stationary (or standby automatic) generator Permanently hooked in to your house wiring and fuel source; operates efficiently; can supply a whole house; convenience of use. Costlier than portable generators.
Automatic transfer switch Powers up automatically in event of a power failure, usually in 10-30 seconds.
Gasoline portable generator Always available when stored on property Generator will need to be refueled frequently; fuel will need to be stored on site; generator will need to be turned off before refueling; no automatic start.
Natural gas and propane Permanent hook-up ensures immediate start-up with automatic transfer switch. Natural gas generators are always stationary. Not available in all areas; may require higher pressure than currently provided to home;

 

Your choice of fuel – gasoline, propane, natural gas – is best determined by the availability to your house. If you receive natural gas, then a hook up to that supply line is the most cost efficient and expedient choice. Your service provider will know to check for the required gas pressure and will advise you on suitability.

A common option is to select a bi-fuel generator – natural gas and propane – which gives the homeowner more flexibility. Diesel generators are the most efficient and maintenance free of all types, however they are the most costly option of all choices.


RV Generators

Rv season is here. RALCO Electric can repair any size RV generator in our new indoor facility to get you back on the road and enjoying your roadtrip




Generators to be used in an RV are constructed to meet specific requirements for providing power when out in the wilderness or on the road, or at a park that does not have hookups. They use gasoline, propane or diesel as a fuel source and have become quite efficient in achieving noise reduction, something your campground neighbors will thank you for. And of course, mounting the unit on sound-absorbing thick rubber pads will reduce noise levels even further. Be aware that the National Park Service has sound level requirements!

  • Gasoline RV generators are the most economical and are very well suited for Class A and C motor homes with single or dual air conditioning, fifth wheels, travel trailers, sport utility trailers, horse trailers and industrial vehicles.
  • Diesel generators are highly efficient and produce more horsepower and torque at steady speeds. Running on cost effective diesel, they operate at a constant low engine speed with superior air flow for cooling.

Our service area covers eastern and central Massachusetts, Rhose Island, southern New Hampshire and Maine.


Marine Generators

Commercial marine generators are engineered to perform in the most rugged and demanding conditions, when downtime is simply not permissible.

The Cummins Onan and Kohler marine generators that we sell, install and maintain provide the most dependable power available. They are used by the military, by recreational and commercial boaters, and many of the finest yacht builders in the world.

Portable Generators

RALCO sells and services Kohler and Cummins Onan mobile generators. Kohler gas, diesel LP and Idle Reduction products have been engineered by experts to provide all the power you’ll need at even the most remote site.
