A surge protector is a device connected between your electronic equipment and the power source. Once you hook it up with the campground power outlet and your RV cable, it works tirelessly to detect any dangerously low or high levels of voltage. This makes it the first line of defense against all voltage spikes. Connecting a surge protector to the computer will make sure that the voltage from lightning is passed on to the ground. A surge protector is designed to respond to a sudden increase in voltage. SurgeShield. A power strip won't keep a burst of electricity from frying your electronics. 2. To understand the problem, it is helpful to understand something about voltage. Surge protectors work to protect electronics by using a system that diverts energy over a safe threshold to protective component, allowing it to ensure that only a safe amount of electricity passes through each device. Not only does it protect your RV from power surges up to amazing 2800 joules, but it also monitors the power pedestal for dangerously high and low voltage levels that can damage your camper. In most cases, surge protectors are made to look like power strips; however, they are also available in single-outlet and . NB: This example features typical UK wiring. The surge protector contains a varistor, or variable resistor, usually made of a metal oxide. So, while they serve the same basic purpose, they do so in entirely different ways. How does the whole house surge protector work? There is usually some device inside the surge protector that handles . A surge protector acts like a pressure-sensitive valve that opens to let that excess "pressure" flow out of the system and head to ground. Described in Details. Dealing with a surge properly has to be built into the nature of the machine. A surge protector is usually an appliance or electronic device meant to protect electrical equipment from sudden voltage spikes induced by power surges. Joules are a measure of protection Surge protectors offer protection in units called joules. The protector is placed into the main electric panel and forms a redirecting line.
