5.2.9 ELECTRICAL CORDS
Power cords are rated by AWG number. The
lower the AWG number, the thicker the wire
(gauge). The thicker the wire the more wattage
can travel through it.
Using underrated power cords to supply power
to electrical devices may cause over current
draw, trip a breaker and potentially damage
your device.
Depending on the amp draw or wattage of
your appliance, the gauge of the wire in your
extension cords becomes a factor in the length
of the cord you can use.
Because a wire can cause resistance to the
power flow, the thinner the wire, the more the
resistance. Similarly, the longer the wire, the
more the resistance.
Resistance due to the cord thickness or length
keeps the device from getting the power it
needs. You may have to increase the thickness
of the wire (lower number AWG), or shorten
the cord.
5.3 RESIDENTIAL
The most economical way to supply power during
a power outage is to use a portable generator and
run extension cords into the house to power chosen
appliances.
Never
connect a generator to a house electrical
system without an appropriate transfer switch.
Known as "backfeeding" it is illegal, extremely
dangerous and potentially lethal.
A safer option is to use your generator in a standby
configuration. This requires an electrician to install a
generator sub panel, connected to the house's main
electrical panel. Prepare the generator, run a single
extension cord into the sub panel, flip the switch and
power the circuits you need.
This eliminates the risk of electrical “back feed”,
potentially injuring or killing utility workers repairing
downed power lines.
For standby installation:
please note that
Wallenstein generators have a "
neutral bonded
to frame
" feature, and requires connection by a
certified electrician when connecting the generator
to a house electrical system.
A portable electric generator can provide power for
fridges, freezers, sump pump, furnace fan small
kitchen appliances, power tools, lights and other
comforts of civilization when you are experiencing
a power outage.
When not required for home, portable generators
can be used to power recreational vehicles, or
put to work on construction sites that have no
electrical service, providing clean, reliable power to
operate saws, drills, air compressors, heaters, paint
sprayers and other AC-powered tools.
Electronics
are sensative and may become
damaged if subjected to voltage and frequency
varitations. Wallenstein generators equipped with
AVR (auto voltage regulation) help to regulate
voltage within a range, controlling dips in voltage
that could potentialy damage electronics.
However, appliances that have a reactive load
(electric motors in fridges, furnaces etc) cause a
momentary voltage drop at startup. AVR cannot
reacte fast enough compensate for the short drop
in voltage. Therefore it is important to consider what
loads are connected to your generator along with
your electronics.
For example if your 3000w generator has a 50%
constant load (lights, heaters etc) and a refridgerator
starts up (50% startup wattage) the result is a
momentarty voltage drop that could damage
sensative electronics.
Decreasing your constant load or increasing
the size of your generator will help the AVR to
regulate voltage. Another level of protection for
your electronics is have them connected to a UPS
(uninteruptable power supply) which will act as a
filter against voltage drops.
5.4 MOVING
5.4.1 TRANSPORTING:
When transporting from location to location, keep
the following points in mind:
•
If the generator has been running, allow the
engine to cool for at least 15 minutes before
loading the generator on the transport vehicle.
A hot engine and exhaust system can burn you
and can ignite some materials.
•
Keep the generator level when transporting to
reduce the possibility of fuel leakage. Move the
fuel valve lever to the OFF position.
•
Do not lay the generator on its side when moving,
storing, or during operation. A hazardous
condition may be created by oil or fuel leaking.
•
Transport when the fuel tank is empty or nearly
empty. Turn the fuel line off.
•
When using ropes or tie-down straps to secure
the generator for transportation, be sure to only
use the frame bars as attachment points. Do
not fasten ropes or straps to any portions of the
engine or alternator.
