I just bought a used dryer on Craigslist that has a 4-wire plug (14-30). My apartment has a 3-wire receptacle (10-30R). Is there a safe way to switch the plugs without an external ground?
I live in an apartment complex so outside installations are out of the question. The installation manual
provides instructions for switching out the plug but stipulates in the 'Optional 3-Wire' section on page 9 that the previous steps are viable only if you follow codes. My state follows the 2011 NEC codes without alterations and, as far as I can tell, this means that it's legal for me to convert 4-wire to 3-wire because of the older model plug but it still has me a little bit worried.
Electrical engineering is a inside baseball to me but it seems that some internet commenters are worried that wiring the ground back into itself could electrify the frame. I've also read that bonding straps alleviate this problem somewhat but wouldn't this just create a pathway back into the wholly metal frame anyway?
Additionally, I called my leasing office and they apologized profusely for not knowing the rating on the plug. My dryer offers the option between a 208v/120v connection and 240v/120v connection so is it is within reason that the utility closet could provide enough power for the heating element in the dryer? Or should I just DTMFD at a recycling center and buy an older three-prong model on Craigslist? I've seen some go for >$50 and I'm guessing that's cheaper than hiring an electrician.
Snowflake: I'm somewhat poor and unemployed at the moment and I'd like to minimize the chance of accidentally electrocuting myself, my girlfriend, or our cat due to my incompetence. I'd also like to be able to pay rent for the next month ;_;
Thanks for your time!
(but sort of the opposite)
