If you have experience overload or power failure with your RV then an RV surge protector will be your lifesaver. So, what is the difference between RV surge protectors?
If you do not use a surge protector for an RV, then your only protection against surges from outside voltage is the fuse protection built into your camper. These usually range from 15 amps to 30 amps and are about as strong as the small circuit breakers in your house. But these only work when they sense that there isn’t power going to them.
If you have a surge protector connected to your rig then it will divert the surges to the ground when they occur. A good RV surge protector will have a very quick response time, some as low as 2 nanoseconds which is almost instantaneous in comparison to the human reaction time of 220 milliseconds.
There are different types of RV surge protectors in terms of what they can handle.
A Standard Surge Protector (SP) for your RV can usually handle surges up to 20,000 volts. A 120-volt surge can occur in a couple of different ways from lightning strikes, wiring issues, and other things as well. So even though the RVs are usually at ground potential, they still might be able to experience a surge because of these possible issues.
A Complete Surge Protector (CSP) can handle surges up to 100,000 volts. Electronic devices with sensitive circuits that require clean power can be connected to this model.
A Power Surge Protector (PVP) is capable of handling surges up to 250,000 volts and is recommended for RVs with sensitive electronics like an air conditioner, furnace, and electronics.
An uninterruptable power supply that has surge protection built-in is another option for protection against voltage spikes.
