CRAO is considered a stroke of the eye. Studies show that about two-thirds of patients have underlying high blood pressure and one-fourth of patients will have significant carotid artery disease (plaque with narrowing of the artery lining), cardiac valvular disease or diabetes.
Electrical pressure is measured in volts, or voltage. All electrical devices are rated for specific voltages. Most devices and small appliances in a home are rated for 120 volts, while high-voltage appliances, such as electric dryers, ranges, and many baseboard heaters, are rated for 240 volts.
An average size home requires from 5000 to 7000 watts to power essential items. Step 1: To determine your needs, total the watts for the items you would like to run simultaneously. This. provides you with the number of continuous or running watts your generator must supply. Step 2: Now select the largest number of starting watts assigned to the items you wish to use. Step 3: Total these two numbers and this will indicate the size generator required to meet your needs . continuous and surge wattage. If amps are noted on the device, you can calculate watts by multiplying amps times the voltage. example, a 7 amp device on 120v AC current would equal 840 watts (7 x 120 = 840).
