I blew a MOV

I'm having a problem finding a replacement for this weekend..

Long story short it's in a power conditioner and it was connected to a generator when I was adjusting the governor and I saw my voltage meter shoot to 180Vac and it was too late.. the PC has a total of 3 MOV's for the outlets..

For those in the U.S. radio shack has a MOV but they don't list specs..

What I got from the other good (or reduced function) was the specs of it but I'm having a hard time finding one online.

printed on the MOV is this:

14D201k

Farnell have a good range of MOVs and usually parts in stock, so do Digikey.

I'm trying to understand one thing.. clamping voltage.. is that when the device starts to shunt any extra voltages to ground?

All done
