On the other hand, large RVs usually have 50-amp service to power their more lavish setups (think double AC units, washer/dryers, etc.). 50-amp plugs have two 120-volt hot pins, a flat neutral pin, and a round ground. A 30-amp RV can handle up to 3,600 watts; a 50-amp RV puts you up to 12,000 watts, so the increase in power is quite substantial.
Send message »If you inputted 110VAC at 0.68 Amps your at about 75 watts, which equates to 6.88 DC amps. You can take that figure and input it into our Calculator - Sizing a 12 Volt Battery to a Load. Ideally, you should input the hours you intend to run the inverter for, but i can tell you the 75 Watt load will drain the battery 50% in about 6.5 hrs.

Send message »· Calculating Electrical Usage in the Workshop. When electrical circuits or subpanels are added to an electrical service, the total load must not exceed the service rating. Gener- ally, older homes have 100-amp service and newer homes have 200-amp service. If you are not certain about the service, look at the main circuit breaker in the service.
Send message »Load center fundamentals: Know your load center. Every building and home utilizes electricity for lighting, receptacles, and appliance loads. A load center is used in residential and light commercial applications to distribute electricity supplied by the utility company throughout the home or building to feed all the branch circuits.
Send message »Lighting circuits may be designed for only 15 amps; To calculate the load requirement for a circuit, first add up the wattage of all the electrical devices that will be on the circuit. Then, divide the total wattage by the voltage of the system, typically 120 or 240, and that will give you the required current or amps.
Send message »A voltage regulator is a system designed to automatically maintain a constant voltage. A voltage regulator may use a simple feed-forward design or may include negative feedback.It may use an electromechanical mechanism, or electronic components.Depending on the design, it may be used to regulate one or more AC or DC voltages.. Electronic voltage regulators are found in devices such as ….

· Your main panel may be 100 amps, and everything in the house totals up to 200 amps, but you may only be using 50 amps at any one time! For example you may have an electric heater which is 20 amps and a window air conditioner which is 20 amps. Do you have both of ….
Send message »· Newer homes may have 150- or 200-amp service. Very large houses can have 400-amp service. The increase in amps over the years has kept pace with the number of new electrical appliances. The amps listed on the main circuit breaker in the panel box determine the maximum amount the house can safely use. Each circuit in the house is also rated by amps.
Send message »Amps = Watts ÷ Volts. After the steps above the final formula for converting horsepower to amps is: Amps = HP × 746 V × η × PF. Thus, the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor.
Send message »Amps. Amps measure the flow of electricity as an electric current. You should think of electric current as the flow of water through a hosepipe. The more water flowing through the hosepipe, the stronger the current is. Volts. Volts are the measurement used to determine how much force is needed to cause the electric current to flow.
