Bear in mind that many of these effects are essentially dependent on length of conductor involved and fragility of the equipment in question. A longer conductor will tend to have more current induced in it (hence the vulnerability, as it mentioned in the report, of long transmission lines to damage, including, you'll note, buried cables) and a larger conductor will have less resistance, allowing larger, potentially destructive, currents to flow. That's probably why compressor motors, like refrigerator/freezers, took some damage in their testing: in most houses, those are the strongest motors, which can be loosely correlated to the size of wire in the motor for a given voltage. Most household devices that aren't connected to an antenna -- a widget whose sole purpose is to suck down radio-frequency energy -- will survive an EMP with no more damage than a possible need to restart it.
This isn't a high-probability event, either. To get a wide-area EMP, like the "70% of US power infrastructure" the report discusses, you'd need to detonate a high-yield device in the upper atmosphere, which means needing not only a decent-sized nuclear weapon, but a reliable, high-payload missile with the legs to put the device in the ionosphere over the Eastern U.S. That's an engineering feat *far* beyond anyone but France, the UK, the US, Russia, and China. None of those (tinfoil hattery about the latter two notwithstanding) is at all likely to try and drop a nuke on us. North Korea can't even get a medium-range Taepo Dong-2 off the pad and in the air for more than about two minutes before they auger in or blow up, much less toss a high-yield device another several thousand miles and have it go off in the upper atmosphere.
This report, while it makes some useful conclusions, has an agenda: if a panel of distinguished folks whose job function is to figure out the threat of EMP attack on the US comes back and says, "Nope, this is pretty unlikely to happen on a nationwide scale, so let's just get some broad generic plans for local or small regional effects in case some bampot *does* actually set off a truck-nuke in downtown Peoria," they're going to look like fools to the people who paid for the study.
