It will work for any single phase 240v with a steady state current draw of 30amps or less needing a 3 wire connection (black + red+ ground) **Q: Do you know if i can use it to backfeed house, gen l6-30p to 10/3 > ac 30amp dis-connect? thank you for your help.** A: I’m not sure I understand the question. If you use a 3 wire twist lock you will only have 120 volts, you need 4 wires for 240. Why do you want 30 amps for a 120 volt circuit? **Q: what type of prongs are on the unit. what type of receptacle is needed? e.g. nema 6-30r or ???** A: The prong on this unit is NEMA L6-30P, so the receptacle needed is NEMA L6-30R. **Q: Trying to power server from 240v 30a source. psu takes 110-240v. receptacle is nema l6-30 and need standard american 3 prong female. safe / unsafe?** A: Need more info to help you. Check if your source is 240/208 volts or 120? As #10 this pre-wired cord has only 3 wires, neutral, hot & ground it will carry up to 30 amps. The plug you add should also be 30 amp comparable but will only transmit either 240/208 or 120 not both. For both you’d need 4 wires & appropriate plugs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well Made For Up To 30 Amp Use *by S***N on December 29, 2025* I do like for quality of this cord for use as 249 volt for use of medium EV charging speed on my dual voltage EV charger.
