is the prong 3 prong twist lock prong size different between 30, 20 and 15 amp? I bought a 30 amp put it will not fit in my existing receptacle.
BEST ANSWER: What you want to look for is the code for the plug. L5-15, L5-20, L5-30 are designed for 15, 20, and 30 amps respectively. I bought some of the L5-20 cords and they are 12AWG, which is about right for a 20 amp circuit. If I had purchased 30 amp cords I would have wanted to see 10 or 8 AWG.
