how much benefit would I get by using the surge protector/regulator or do I really need one?
ANSWER: Hi Jerry, in my personal opinion all RVers should have some sort of voltage protection for their RVs. All it takes is one voltage spike (surge) on an unprotected RV to cause thousands of dollars of damage to the RV's appliances and electrical systems. So investing in a voltage protection device for your RV makes financial sense, just like having an insurance policy on your RV.
Basically, there are two types of Voltage Protection Devices you can get for your RV.
Surge Protector: These devices provide basic protection of your RV's electrical systems from Power Surges (Spikes) caused by lightning Strikes on nearby power lines, etc. Normally these are simply devices that you plug into the shore power box directly and then plug your RV into the device.
These Surge (spike) Protectors such as the SSP Series from Progressive Industries are readily available and can cost less than $100.00 for the 30 Amp model and less then $110.00 for the 50 Amp model.
Again these devices only provide basic protection to your RV and do not prevent damage to your RV's electrical system from prolonged exposure to high or low voltage situations.
