I'm looking to power a Prusia i3 3D printer with RAMPS 1.4 from an eTopxizu Dc 30A 360 W Regulated Switching Power Supply, at the moment I'm looking at how to connect it (safely) to a United States wall outlet.
I've seen that you can cut off the female end of a standard power cable for a PC and strip the insulation to reveal three insulated: wires, ground, positive and minus respectively.
And then those would be connected to a spade electrical connector which has a rating for a particular kind of wire.
(And yes, I know this would likely be the last step in the process after wiring everything up before plugging it in, and safety dictates that I NEVER NEVER touch the leads when it is plugged in; I plan to cover the back end of the device with a 3D printed cover and a switch so nobody touches the leads.)
But my question is, that given the type of wire I intend to use to connect it to the US outlet, what sort of rating should the spade connectors have?
