This holds true even in the UK where they speak funny. As for the formula, it's standard around the world - P=EI where P equates to Power in watts, E equates to Energy in Volts, and I equates to Intensity in amps. For more products to power your RV experience, c heck out the extension cords from GearIT.The recommendations in my message are for copper wire (not aluminum) as delineated in the NFPA's NEC Ampacity Workflow chart, Table 310.16 on page 3 in the most conservative cases. However, for safety and performance, you want a quality product from a company that specializes in selling top-tier, durable power cords you can trust. Where Can You Find a Quality 30-Amp Extension Cord? You can purchase a 30-amp extension cord from most hardware stores. Limit your cord length to no more than what you need whenever possible. The longer the cord is, the higher risk for voltage drops. Will Length Affect the Power?Įxtension cords can reach as far as 100 feet. At a minimum, you need a 10-gauge cord, such as this heavy-duty 30-amp 250-volt generator extension cord from GearIT, designed for RV outdoor use. Additionally, the cord will likely heat up, creating a potential fire hazard. If you use an adapter to connect a 14- or 12-gauge cord to an RV that needs 30 amps, the voltage will drop, decreasing the amount of power you receive and making it impossible to keep all your appliances running. The most common sizes and the amps that can safely pass through them are: The gauge of an extension cord refers to the diameter of the conductors within the cord. While the adapter may allow you to physically plug it in, the cord gauge is likely insufficient to handle the amps that will run through it. A common mistake people make is to use adapters to connect a smaller extension cord to a larger plug. That is substantially more than the orange cord you see in every garage can handle safely. How Much Power Do You Get With a 30-Amp Cord?Ī 30-amp circuit provides up to 3,600 watts of power. To power your RV at home or camp, you need a cord that can handle the wattage of a 30-amp plug. A 30-amp system does not have a heavy electrical load, so you mostly see those with a smaller RV carrying minimal accessories. Most RVs come with a 30- or 50-amp electrical system. When might you need 30 amps and an extension cord to access it? The most common example is to power an RV. In the same vein, when you use an extension cord that cannot handle the electrical current provided by a 30-amp plug, you will not have sufficient power to run your equipment. What happens when you plug in an appliance that needs more power than your outlet can provide? The breaker pops. When Do You Need a 30-Amp Extension Cord? So, what needs 30 amps of electrical power and when would you need an extension cord to access it? Consider this brief guide your answer to that question. The word "amp" refers to the unit of constant electrical current needed to power something. A 30-amp extension cord is a cable used to power large appliances and recreational vehicles that need more power than a standard extension cord can provide.
