The Peace-of-Mind of a Home Generator
As summer draws to a reluctant close, responsible
homeowners should start making an early evaluation of their
home needs for fall and winter. Every year, thousands of
Americans deal with power outages firsthand. Many homeowners
keep generators on hand in the event that the lights go out.
A Safety Blanket
After particularly strong wind or ice storms, power outages
can stretch for days or even weeks depending on the severity
of the damage and the number of people affected. Running a
generator can be an effective way to power your home's core
systems and essential appliances while utility crews work to
restore regular service. Types
Every generator has two primary components: a
motor that burns fuel to supply power and a generator head
that converts that power into electricity. Most generators
utilize engines made by respected companies such as Yamaha,
Honda, Ford and GM. In general there are two different kinds
of generators: portable generators and standby generators.
Portable generators provide power in remote
locations or emergency situations for short periods of time.
These generators have built-in fuel tanks and standard power
outlets that can be hooked up to regular extension cords. The
best portable generators have large fuel tanks for increased
running time, a fuel indicator gauge and multiple outlets to
plug in all essential devices.
Standby generators are installed permanently as an
emergency power source for a business or facility. Standby
generators are hard-wired into a building's electrical system
and typically have a direct fuel line (gas or propane). While
standby generators are most often used by businesses,
hospitals and the like, residential models are available.
While more expensive than portable generators, they are sound
investments in areas that experience frequent power outages.
Usage
When buying a portable generator for emergency situations,
it's important to look at models designed specifically as
backup power systems. Styles of generators to avoid:
Recreational/Camping Generators are designed for
camping or tailgating. While their compact size makes them
ideal for recreational outings, they do not generate enough
electricity to power more than a few small appliances.
Additionally, their relatively small gas tanks would require
refueling every few hours or so.
Jobsite/Professional Generators are larger than
standard portable generators and often must be towed by truck.
While their larger fuel tanks allow for longer continuous
running, typically the power output of jobsite generators
exceeds the needs of a single home.
Fuel
Gasoline is the most common fuel for portable
generators. Gasoline should be stored in approved containers
and should not be stored in the house. Gasoline cannot be
stored indefinitely, so the stored gasoline stock should be
used and replaced every six months or so.
Propane is a popular fuel for both hard-lined
standby generators and portable generators. Propane is easier
to store than gasoline and just as easy to replace.
Diesel generators are more reliable and less
expensive to operate than propane or natural gas generators,
but the fuel is not clean burning. Typically used in larger
commercial generators, diesel must be stored in proper
tanks.
Natural Gas can be used by both standby and portable
generators, but is more common in standby generators.
Power/Generator Size
Voltage is essentially a measure of the "pressure"
of an electrical current. Standard household current in the
United States is single phase, 120 volts. Most houses have
120v/240v service - two 120v circuits that can team up to
provide 240v for power-needy appliances (water pumps, air
conditioning units, electric stoves etc). In general, 120/240v
generators should supply a sufficient current for most homes.
Wattage measures the "volume" of electricity created
by a generator. Depending on the wattage output, generators
can power everything from a small lamp to a number of big
appliances. The smallest generators produce around 800 watts,
while large commercial generators can pump out 500,000 watts
(or 500 kilowatts) or more.
Before buying a generator, make sure you have an accurate
idea of your power needs rather than rough estimates. To keep
your costs down, limit your choices to those appliances or
devices that will be truly essential during a power outage.
Many appliances list their power requirements on nameplates or
in their instruction manuals. Remember that many appliances
require additional wattage for starting the equipment (see
example table below). The initial load is brief, but this is
the wattage that should be used when calculating overall use.

| * Wattage numbers are
estimates. They will vary based on the wattage rating of
the tool or appliance being used. |
As an alternative, you can hire a certified electrician to
measure the wattage needs of the systems and appliances in
your home. Some general guidelines:
Medium-sized portable
generators (3,000-6,000 watts) will power multiple core
appliances such as your refrigerator, sump pump, furnace fan
and portable heater.
Large portable generators
(7,000-9,000 watts) will restore power to multiple rooms in
your home (minus a central air conditioner).
Extra Large portable
generators (10,000+ watts) will supply enough electricity to
restore power to small homes, including some central air
conditioners.
Safe Operation
Generating power on your own is not risk free. Exhaust from
generators contains carbon monoxide (CO), fumes that can cause
asphyxiation in interior confines. Carbon monoxide is odorless
and invisible to the naked eye, and can be difficult to clear
from confined spaces. Every storm season hospitals around the
country admit patients harmed by improper use of home
generators.
- Never use a generator indoors or in attached garages.
Always operate the generator in well-ventilated areas
outdoors. Make sure to set the generator up away from the
home's air intakes and any open doors or windows. Keep the
generator at least 10ft away from the home and be mindful of
wind direction that may push CO into the house.
- Protect the generator from direct exposure to rain and
snow.
- Use only heavy duty, outdoor rated extension cords with
an appropriate wire gauge.
- Do not attempt to exceed the generators stated wattage
output.
Quick Tips: Hosting a Football Party
It's September, which means we'll soon be witnessing the
changing of the seasons: not summer fading into autumn, but
baseball giving way to football. Here are some basic tips for
hosting a successful game day get-together.
- Rain or Shine: If the weather's nice, make plans
to grill outside pre-game or during halftime. Weather
forecast looks a little grimmer? Change the menu to dishes
you can cook in the kitchen. If you're a true die-hard you
can take your game to the next level and barbeque regardless
of rain, wind or snow.
- Cook Before and Serve Early: No host wants to
miss the key moments in the game while manning the stove.
Cook dishes before the crowd arrives and have food set out
ahead of time. Hot dishes can be kept warm in the oven.
- Food Setup: Ideally you should pull a kitchen or
dining room table into one corner of the living room and
serve food buffet style. Leave room on either side of the
table of possible, and remember to provide plenty of plates,
silverware and napkins.
- Traffic Flow: Often the temptation is to cram as
much seating into your living room as possible. Remember
that your guests are going to be up and about throughout the
game. Set up chairs and couches with adequate walking paths.
- Garbage and Recycling: Set up bags for garbage
and recycling in accessible areas of the kitchen. You may
want to have an additional garbage container in the living
room as well. Make signs for each.
- Support the Fantasy Football Diehards: Fantasy
football has become increasingly popular amongst even casual
football fans. Keeping a laptop or desktop with an internet
connection nearby will please those avid stat-trackers.
