switching from isolated ground receptacle


I'd like to understand the effort required to switch to a grounded receptacle from an isolated ground recepatacle before I call the electrician. It's on a dedicated circuit. To be more specific, do I need to pull a 14/2 wire to replace the 14/3 wire?

My 2005 is outdated.I have it in the computer.Time flies.I'm not going to buy a new one though.Table 210.21(B)(3)sounds like a 15 amp receptacle is ok for 20 amps. Sounds like a 15 amp duplex could overheat on a 20 amp circuit without tripping the breaker.I would think a 20 amp receptacle on a 15 amp breaker with 14 or 12 gauge wire would be safer.Consumers don't know what they're plugging in,so you have to rely on the breaker.I'm not a electrician,and I didn't stay at a Holiday Inn Express either!
Jea48,Am I backwards,or them?Two heaters or other plugged into
that one 15 amp duplex on a 20 amp breaker.Sizzle,glow,and worse.
Also,who's table 210.21(B)(2)for?The consumer that looks at the power consumption of the item they're plugging in? I have about 125v nominal.At 20 amps that's 2500 watts on a duplex they say is good for 12 amps or 1440 watts at 120v.They drive me crazy.
Maybe,I need to stay at one of those Holiday Inn's,and bring a new NEC code book with me,plus a big bottle of aspirin.♫
