Safety Fuse Setup

Hello everyone!

So I pulled an electric heater out of an AC unit and have it wired so that a plug from a 120V outlet is connected to it's two wires. I have two questions.

1) The resistive, 9.3 ohm heater only has two leads which I have connected to the hot leads from the cord that runs from the outlet. What do I do with the grounding wire? I am assuming I connect it to the metal casing that the heater will go in.

2) I need to install a fuse for safety reasons. I can't find any fuses that I can install in line with the wire. If you have any experience with this or any suggestions I would greatly appreciate it. The closest thing I have found is a fuse switch box.

Thank you for your time!

Your house circuit breaker is 15A it should do the job.
20A fuse should be fine just buy fuse holder and solder it to the wire in series.

1)yes.
2) you can buy a fuse holder that mounts in the wall of the box.
3) don't forget to install a fan or your heater will melt like a cartoon Nazi face in an Indiana Jones film.
4) The circuit breaker operating the wall outlet should work just fine.

One addition to #12's list:
5) use a thermal breaker in case things get too hot. ;)
