What is bypassed (assuming the rest of the rig is protected by some kind of hardwired or portable power management device) is high/low voltage conditions or improperly wired outlets...
An A/C unit is much more vulnerable to low voltage than an aux heater element...
While you can certainly verify proper wiring before plugging in with a simpler plug in tester, any surge or voltage out of normal is not stopped.
Haven’t seen a Surge Guard or similar meant for 20A service, but at least be aware what isn’t covered.
