I will double check the voltage coming out of my adapter cord after plugging it into my friends dryer outlet to make sure that I am getting 240V out of one prong.so when I check his outlet I should 120 between each hot lead and the neutral, and when I plug my cord in I should see 240 volts coming out of my "single" hot lead when linked to my neutral lead. I did this after doing some reading and busting out my multimeter to check my dryer outlet (a 3-prong style).240 volts coming out of one lead for a 3-prong outlet and 120 volts coming out of one lead each for a 4-prong outlet.if you go across both hot leads in a 4-prong then you see 240 volts. so on the 3-prong female plug of my adapter cord I have run the two hot leads (one red and one black) to the corresponding hot straight blad, the neutral lead (white wire) to the opposite straight blade, and the ground (green wire) to the "U"-shaped ground blade. 1-48 of 344 results for 'dryer plug adapter 4 to 3 prong' RESULTS 20Inch Nema 10-30P to 14-30R Dryer Adapter Cord, STW 10-AWG Heavy Duty 3-Prong Dryer Male to 4-Prong Dryer Female Adapter, 10-30P to 14-30R with Additional Green Ground Wire 2,039 Save 15 169919.
