Wiring up my GFCI cord - need advice

[breeves2245]

Wore myself out trying to Google for this answer so I figured I would try here. I bought a used inline GFCI cord, 240v, 30 amp, 4-prong to use with my biab system. The cord does not have a plug end, just wires. Since the prong end is molded, I cannot take it apart to figure out the hot, neutral and ground colors. I got green is ground, but not sure about the other three. If I had to guess, black and blue are hot and brown neutral. But with 240v, I ain't up for guessing. I contacted the manufacturer, Technology Research Group, but no reply to my email yet. Can I test with a multi-meter? I'm very electric ignorant, so I would like to get it right the first time.

Thanks.

More likely black and brown are hot, and blue is neutral. In any case, you should test with a multimeter to be sure. Set meter to read ohms on a high resistance range. Breaker must be on for testing to work.

Brew on

So as I understand you, you have a plug (the bladed bits) on one end and bare wires on the other? If so look up your plug type to find the hot and neutral wires and use a continuity test to determine which blade is which wire.

I went back to the web with different search parameters and found almost all answers were the blue was neutral. Cord is made in the Honduras, so maybe that is international electric colors. Wired it up that way and it works fine.
