Basically I have an uninterrupted power supply (UPS) which has a 20amp plug and I know that the load on the UPS will NEVER exceed 15 amp (Bought it mainly because it can attach more battery units to it for extended runtime).
Anyway since I am moving to an apartment that does not have any 20amp outlet, and since I know that the load will NEVER exceed 15amp, I want to enforce this via a fuse/breaker inline or in the outlet so that it WILL trip before too much power is drawn from the outlet.
So I am wondering if such thing exist or if there is any recommendations here?

Get a 20A to 15A converter cable, like this one: http://www.amazon.com/Conntek-1F515520-1-Foot-15-Amp-Adapter/dp/B00439KIF6
It is perfectly safe to plug a 20A device in to a 15A receptacle on a 15A breaker. If your device draws more than 15A, the breaker will trip. You can reset the breaker and try again, with a lower load. If you never exceed 15A draw, you'll be fine.
15A is a lot for a computer. You can use a Kill-A-Watt to measure your actual load, if you're curious.
