A:Answer Hi DLK1.
Glad that you ask if this dryer requires four prongs or minimum volts.
Use a 4-prong plug for a four wire receptacle, NEMA type 14-30R) at a minimum of 120 / 240 volts, 30-amperes with three No. 10 copper wire conductors terminated with closed-loop terminals, open-end spade lugs with turned-up ends, or with tinned leads.
Have a great day.
