A 50amp lesson learned
We have had our new 5th wheel for about a month now. It's our first RV with 50amp service. All previous have had 30amp. I moved it about 50 miles yesterday to a new RV park. When I arrived I plugg...

A spike is a fast rise in voltage, lasting generally less than 1 60th of a second, Spikes on a 120 volt line can easily hit 1,ooo volts. A SURGE can be seconds, or even minutes, not as high as a SPIKE but (Typically only about double the proper voltage) but the Spike supressor can not absorb that much power.
What you're calling a "surge" is properly called a swell or perhaps simply over voltage.
Surge - 1-100 us
Temporary Over Voltage (TOV) - 100 us - 8 ms
Swell - 8 ms - 1 min
Over Voltage - > 1 min
Here's a whitepaper, which discusses these common industry terms.
