50 amp surge protector

An EMS (electrical management system) is SO much more than a surge protector. They perform multiple functions. In our previous rig, the Progressive industries saved us from appliance damage on two or three occasions: 1) a lightening strike less than 100 yards away which caused a spike, an outage, and a surge when the power came back up; 2) very poor 50 amp power at a place in east Tennessee. The voltage dropped below the threshold on one leg (would have damaged the AC on that leg) and the EMS took us off line (the park owner ended up scheduling a complete rebuild of their electrical system); and 3) a faulty 50 amp breaker in another park that would intermittently drop the voltage and/or drop out altogether (again, the EMS took us off-line until the situation was remedied). In our new rig we had an incident last week. We are staying on a military installation and contractors were clearing vegetation from the fence line behind us to prep for new fencing. A worker backed a Bobcat over the transformer for the FamCamp. The power crew told me that the transformer had been pushed off its concrete slab and two 13kV lines were shorted. I don't know what happened downstream (our side), but the EMS in our new rig took us off-line until we had clean power again (on an 85 degree day with 75% humidity!).
