RV Electrical Cord and RV extension Cord Safety

Your RV is loaded with many of today’s modern conveniences that we all know, and have grown to love. We have become accustomed to these electrical devices and appliances. You should have a basic understanding of how your RV’s electrical system works, including the RV extension cord, if you plan to use it on a regular basis.

RV Voltage System

Your RV has an electrical system that is 12 volts and a system that is 120 volts. There is a battery powering the 12 volt system, or in some cases, many batteries. This provides the power to start your furnace, water heater, and refrigerator, your water pump, and the majority of light in your living area. The 120 volt system receives power from a generator or an RV electrical hookup plug. This system powers items used on a daily basis such as your TV, kitchen appliances, and other electrical appliances.

RV Amperage

The majority of RVs have power cords to plug them into electrical pedestals at campgrounds, or other available electrical hookups. There are two amperages, a 30 amp and a 50 amp. There are three prongs on a 30 amp, and four on a 50 amp. More electricity is able to be used at once with 50 amp. When unable to reach the electrical hookup with your power cord, be sure to use the correct RV extension cord according to what amp you have. While investing in an RV extension cord, be sure it is as short as possible for voltage drop avoidance. It is wise to purchase a 50 amp to 30 amp adaptor, because many electrical hookups at places like campgrounds only have hookups for 30 amps. Keep in mind, 50 amp capacity is able to be adapted down to a 30 amp cord, however, 30 amp must not be adapted to a 50 amp cord.

Polarity Tester Before Plugging In

It is smart to a test with a polarity tester before plugging everything in. Make sure all wiring is good where you are planning on plugging your RV in, with this common and affordable tool.

Next, be sure everything in your RV is switched off. Check to be sure the RV extension cord is plugged in firmly, and switch it on. For better safety measures for your RVs electrical system, install a surge guard.

All these tips could save your RV, your budget, and possibly your life.
