starting amps for air conditioner

Here is how big a generator 5000 BTU air conditioner need: Low-efficiency units (EER rating 8) need a 625 W generator. Central air conditioning requires between 208 and 240 volts to operate and draws between 15 and 60 amps depending on the size. RLA on the tag is 21.2 amps. 5000 BTU AC is recommending for rooms less than 200sqft. I need the starting amp draw so that I can choose a suitable generator to power the unit. For instance, let's assume an Air Conditioner has a BTU capacity of 10,000. But why does an AC have a hard time starting up in the first place? Most central air conditioners use between 15 and 60 amps, and about 240 volts, while a window AC unit uses anywhere from 3 to 20 amps and 120 volts. Coming in at 14,000 BTU and an EER rating of 9.8, this portable AC is an excellent choice for any room that's 450 to 600 square feet. Customer: OK thanks. At startup it will use far higher, and when fully "warmed up" it may use slightly less. I only have a 20 Amp circuit breaker and it works well with the cooling of the air conditioner. I assume that the 7.6 is running. Easy Start your A/C without buying a second or bigger generator or inverter; Run 2 air conditioners on a 30-Amp cord. The requirements for other types of AC units vary depending on the model number and size. for the LG portable air conditioner model : LP0711WNR The electrical information on the box states that the unit draws 7.6 amps , but does not designate this figure as running or starting. Each employs a 4-part start ramp sequence that is self-optimizing, resulting in the lowest possible start-up current. Units require anywhere from 15-60 amps depending on how many tons they are. Window-unit air conditioners typically have a range between 5,000 and 18,000 BTUs. Not every 3 ton air conditioner consumes the .

An RV rooftop 16 KBTU, 120 volt compressor can now start with under 20 amps of current. Most 5,000-BTU air conditioners use 5 amps, and when plugged into a 110-volt outlet, the unit uses 550 watts. When the engine is running for most of time, the air conditioner requires at least a significant amount of energy to get started and keep running. Sound level as low as 74 dBA with accessory sound blanket. As a rule of thumb, you can use 0.8 amps per 1,000 BTU to estimate the amperage of a 115V window air conditioner. For the running time portion, those figures will lower to approx. A btu air conditioner of this size uses about 550 running watts per hour, well within the maximum 2000 watt range. To start up a roof air conditioner, it can draw 16 amps max but will only use 13 amps once running. The start surge is five times the continuous electrical load, meaning that you will need 275 amps of direct current power to start the five-amp air conditioning unit and a continuous 55 amps to keep running it. For an average 5000 BTU air conditioner, you are looking at between 1200 and 1500 watts just for the start-up portion of the operation. Starting wattage of a 5000 BTU unit will surge between 1200 watts and 1500 watts for a second. Here's how we can calculate how many amps such 10,000 BTU air conditioner draws: I (in Amps) = 10,000 BTU / (12 x 115V) = 7.25 Amps We see that this AC unit uses 7.25 amps to deliver 10,000 BTU of cooling power. For practical purposes, it takes 11 amps of DC power to successfully run a 1-amp AC powered device. Also, more than likely, you will have other things running on your generator. The 9,200 BTU air conditioner weighs 87 pounds and delivers excellent cooling at 9.6 amps (106 amps DC) on low speed using a 2,000 watt generator or inverter (11.7 amps on high).
