Re: Outlets in a 1950s house
In addition to what dj1 said, a freezer should never be plugged into a GFI-protected outlet. The code allows for dedicated circuits with a single receptacle (not duplex) without GFI protection, even in areas that would otherwise require GFI protection (such as in garages and unfinished basements). If the circuit is rated for 20A, the single receptacle must also be rated for 20A. I don't see a good reason why you couldn't plug the freezer into a 20A circuit; I suspect that the manual means it must be at least 15A.
What really baffles me is the requirement specifying a "three or four prong outlet." I've never, ever heard of a four-prong outlet on a 120V circuit!
If you plug the freezer into a shared circuit (shared with other outlets or devices) it won't trip the breaker if that's all that's connected. But if you do overload the circuit or cause it to trip somehow, you can end up with a freezer full of spoiled food and a soaked carpet if you don't notice the problem right away. That's why you absolutely should have a dedicated circuit for the freezer. The cost of having a dedicated circuit will likely be less than the cost of losing a freezer full of food, and certainly less than the cost of repairing water damage.

The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
