Electronic Devices, High In Rush Current, Surges
I've often heard that it is a bad idea to have a computer and an air conditioner, vacuum cleaner, microwave, refrigerator, etc... on the same circuit. I really do not understand why it is a bad idea to have both devices on the same circuit. I understand the importance of a surge protector for a computer to help divert excessive voltage resulting from a failing transformer on the pole or lightning. In that instance, you are dealing with excess voltage. However, I don't understand how a device that pulls 50A or more in-rush current could hurt a computer. If my understanding is correct, the air cond. would pull maybe 50A to start up the compressor and then quickly fall back to approx. 5A. All of that current is going straight to the air conditioner. How could that possibly damage a computer if the computer is not pulling that much power? With in rush current, the voltage remains constant but the amount of current is simply high for a brief moment, correct? How could an Air Cond. possibly pull more voltage than what the transformer on the pole will allow? If anything, I would think that the air cond. pulling a massive amount of power would temporarily create a lot of resistance on the wire that would slow down the current flowing to the computer on the same circuit, creating a sort of short brown out. Could someone please answer these questions?
