what size wiring should i use to wire a plug in for a dryer?
if the dryer rateing plate says 220 volt 30 amp you can use # 10 stranded wire/ romex 2 colored wires and 1 ground (bare) or insulated green wire.
You will need 4 wires to meet current electrical codes..2 black or red wires. (ungrounded conductors). 1 white wire. (neutral or grounded conductor). 1 green insulated or bare copper wire. (equipment ground). Both ungrounded conductors on a 2-pole, 30 amp breaker or fuse. A 30 amp, 250 volt rated receptacle is also required..The dryer will work with 3 wires, but is not up to code, because of bonding/grounding issues
