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?

They need to revise or clarify article 210 in the NEC in my opinion.

Hifitime,
which section?
Article 210 of NEC 2008 has many new changes....

Just one example, NEC pretty much made miltiwire branch circuits a thing of the past.
210.4 (B) Disconnecting Means. Each multiwire branch circuit shall be provided with a means that will simultaneously disconnect all ungrounded conductors at the point where the branch circuit originates.

No changes regarding Table 210.21(B)(3) Receptacle Ratings for Various Size Circuits.
or
Table 210.21(B)(2) Maximum Cord-and-Plug-Connected Load to Receptacle.

My 2005 is outdated.I have it in the computer.Time flies.I'm not going to buy a new one though.Table 210.21(B)(3)sounds like a 15 amp receptacle is ok for 20 amps.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.
