Electrical Systems For Dummies

Typically your big energy sucks run off this system.

Electrical systems for dummies. The 12 volt system is powered by a battery or in some cases multiple batteries and it powers things such as the start up on your water heater furnace and refrigerator plus most of the lights in your rv s living space your water pump your carbon. Electricity flows from a battery in one direction only and some components work only if the flow through them is in the correct direction. Usually it does not run off your batteries and is the big reason many folks are constrained to rv parks. Many home electrical systems include a dedicated disconnect switch that is mounted on an outside wall of the home near the electric meter.

This is called a negative earth system and when buying an electrical accessory a radio for. V i x r. Electric power systems are based on alternating voltage applications from low volt age 120 volt residential systems to ultra high voltage 765 000 volt transmis sion systems. Electrical systems maintenance for dummies now available.

This is the second blog post from before the direct current e newsletter to continue reaching new readers years after its publication. The current in an electrical circuit with a voltage of 120v and 12ω of resistance is 10a. The 120v ac system. This acceptance of a one way flow is called polarity on most cars the negative battery terminal is earthed and the positive one feeds the electrical system.

In the event of a fire or flash flood or if work needs to be done on the system a disconnect switch allows you to shut off the power from outside the home so you don t have to enter the home to turn off the power. In may 2015 this book from john wiley publishing and shermco industries was announced on the ea blog. One rv two electrical systems. The third piece of the puzzle is called power abbreviated p in equations.

The current in an electrical system with 10a and 200ω of resistance is 2000v. A 12 volt dc electrical system and a 120 volt ac system. There are lower and higher voltage applications involved in electric power systems but this is the range commonly used to cover gener ation through distribution and. Your rv has two separate electrical systems.

Rvs use both ac alternating current and dc direct current to power the components of your electrical system. This part of your rv electrical system is just like your house. The three key concepts you need to know before working with electronic circuits are current voltage and power. You ll have the same kind of wall outlets you re used to plugging things into at home.

Current is the organized flow of electric charges through a conductor and voltage is the driving force that pushes electric charges to create current. The 12 volt dc system runs the electrical components of the engine and battery of your ride while the 120 volt ac system runs all the typical appliances and power outlets found on most rvs.
