Some say that the boards "should" have surge protection built-in. No doubt, but there are a lot of appliances with burned out cards sitting in the junkyard. The most common surge protection component is a varistor, which has a finite life. So even if the device was initially protected, you can't assume it will have lifetime protection.


If I was building a house today, I'd want to install a whole house series mode surge suppressor.
