Yes, I'm sure you can. It just requires a wire stripper, and a screw driver.
That said, 12 gage is rated for 20 amps, and less than that if it's a long
run. So, while you CAN use the wire, it's not really heavy enough to carry
the load. It may also very possibly fail a code inspection. You also CAN use
18 gage lamp cord, if you want

Can I use 2/12 wiring for a 240 volt 22 amp hot tub.? I have about 50
feet of 2/12 wire already wired from my electrical panel to outside.
This wire used to be for a pool heater but I no longer have the heater
therefore the wire will carry no other load except the hot tub. I
would connect this wire to a gfci box and the box would have #10 awg
going to the hot tub. can the 2/12 take the load safely?
