Surge Protector
I have a 50 amp Surge Guard that is 7 years old. I am selling it to a friend because I now need a 30 amp. My question is a 7 year old surge protector okay to sell or should I just throw it away. If it...

Only an EMS that costs more than your rig can deal with instantaneous power SURGES (time limited), high or low voltages. My home complete protection system is a military grade + - 40% ferroresonant voltage adjuster plus a 30 amp 240vac rated full isolation transformer.
A miracle?
Hardly.
The unit is as big as a sea chest; 160 lbs and eats 160 watts at idle. I use it when protecting a (then) $15.000 Tektronix oscilloscope.
Gordon Three hits the nail on the head.
My constructed surge protectors use TEN EACH
20 mm 190-volt MOVs
1,500-watt TVS
AND AND AND
3 amp rated Bussman "rice grain fuses. INDIVIDUAL fuses.
I know of no commercial "surge protector" that can compare it's longevity to such massive overkill. And longevity is why this thing exists.
Bussman rice-grain dedicated fuses are EXPENSIVE. But a blown fuse means a discrete component failure so the system is field repairable. The 150-amp Meanwell manual charger I am building has such a system. No chew-and-spit technology. Shi^^^ from China clogs landfills.
Serious buss-board MOVs can cost eighty dollars each. But in an RV grade environment would last a long time, unless their peak-to-peak voltage limit was exceeded longer than what they are rated for.
My military grade sola eats more power than a red headed stepchild
