Question: A friend of mine asked me a question and I have no answer, so I thoughbt I'd raise it here.He wants to install a portable generator as his backup power for his home. His plan is a little unconventional. He doesn't want to use the transfer switch I suggested. Instead he wants to trip the breakers in his breaker cabinet and then run extension cords to a receptacle on the circuit (male connections on both ends) and run the appliances that way. I don't even know if that can be done, but his questin was more about whether or not he'll burn his house down or blow up the fridge.Can anyone answer this?
Can it be done?
Yes, it is technically possible to power appliances using extension cords connected to a generator with tripped circuit breakers, but it is not recommended for several reasons.
Safety Hazards
Electrical Shock
There is a significant risk of electrical shock when using extension cords in this manner. The cords can overheat and cause a fire, or they can come loose and create dangerous live wires.
Overloading
Extension cords are not designed to handle the high current loads required by appliances, such as refrigerators. This can lead to overheating, sparking, and potential fires.
Damage to Appliances
Running appliances on extension cords without proper grounding can damage their electronics and shorten their lifespan.
Code Violations
Many electrical codes prohibit the use of extension cords as a permanent power source. This practice can be considered unsafe and could void homeowner's insurance in the event of an electrical accident. Most generators require a transfer switch to safely connect them to a home's electrical system. Using extension cords bypasses this safety measure.
Risks to Appliances
Refrigerators rely on a sealed compressor system that can be damaged by voltage fluctuations or power surges from a generator.* Other appliances, such as microwaves and computers, can also be susceptible to damage from improper power supply.
Conclusion:
While it is possible to power appliances using extension cords and a generator with tripped circuit breakers, it is strongly discouraged due to the safety hazards, code violations, and potential damage to appliances. It is essential to install a transfer switch to safely connect the generator to the home's electrical system and avoid these risks. Flag for review
