Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.
Depending on the configuration of the cord cap, the green wire is ground, the white wire is the neutral and red and black wires are the 220 volt source.
If wired correctly the red wire will be hot, but any wire can be hot regardless of colour if done incorrectly.

For 120/208v 3 phase system: black, red, blue, white For 277/480v 3 phase system: brown, orange, yellow, gray Phase colors are not stipulated in the code book for the United States. The above colors are used by convention. Neutrals, however, must be white or gray.
The red wire is typically the live wire for a 12 volt system, while the black wire is the ground wire. Always consult the pump's manual or manufacturer specifications to confirm the correct wiring for your specific pump.
The colour red designates that the wire is used as a live wire. The neutral wire is identified as white in colour.
