I'm so glad I have a a HW50C full protector. It won't connect the power if the pedestal has a problem and it will later shut down in a few milliseconds if a problem occurs.
My 160V incident occurred as I was going to bed and without the HW50C I have no doubt everything on standby like MW, TV, HW, charger etc would have been toast. Instead I had a high and short stress moment until I could get the power cord pulled. I knew what was happening because I saw the 160V right on the inside monitor.
I'm sure I was quite a sight running outside at night dressed in whatever...
