need for 20 amp receptacles?

New construction today, master bath circuit is 12 gauge copper with 20 ampere breaker, but the two bath receptacles are 15 ampere receptacles, not 20 amp rated. Sparky replies if only one receptacle is on the circuit, is should be a 20 ampere-rated receptacle...if there's more than one receptacle on this circuit, it's allowed, per NEC, to have only 15 ampere-rated receptacles. True? If so, why? Thanks very much for any insight.

OK, I think I found it. If I am wrong I will gladly accept correction .

2002 NEC 210.11(3)Bathroom branch circuits In addition to the number of branch circuits required by other parts of this section, at least one 20 ampere branch circuit shall be provided to supply the bathroom receptacle outlet(s). Such circuits shall have no other outlets.

Exception: Where the 20 Ampere circuit supplies a single bathroom, outlets for other equipment within the same bathroom shall be permitted to be supplied in accordance with 210.23(A).

210.23 Permissible loads.

In no case shall the load exceed the branch-circuit Ampere rating. an individual branch circuit shall be permitted to supply any load for which it is rated. A branch circuit supplying two or more outlets or receptacles shall supply only the loads specified according according to its size as specified in 210.24 and Table 210.24

(A) 15- and 20-Ampere Branch Circuits

A 15- or 20- ampere branch circuit shall be permitted to supply lighting units or other utilization equipment, or a combination of both, and shall comply with 210.23(A)(2).

Exception: The small appliances branch circuits, laundry branch circuits, and bathroom branch circuits required in a dwelling unit(S) by 210.11©(1), (2), and (3) shall supply only the receptacle outlets specified in that section.

(1)Cord-and-Plug-Connected Equipment does not apply to this

(2) Utilization Equipment Fastened in Place Does not apply to this

Table 210.21(B)(3)Receptacle Ratings for Various Size Circuits

Circuit Rating________Receptacle Rating (Amperes)

15---------------------Not over 15

20---------------------15 or 20

30------------------------30

40----------------------40 or 50

50------------------------50

Scott's commentary It could be argued that this is not the table described in 210.23(A) as referred to in 210.11(3). However, when you read 210.24 it appears to be OK

210.24 Branch-Circuit Requirements-Summary

The requirements for circuits that have two or more outlets or receptacles, other than the receptacle circuits of 210.11©(1) and (2), are summarized in the table 210.24. Scott's note; Bathrooms are (3)This table provides only a summary of the minimum requirements. See 210.19, 210.20, and 210.21 for the specific requirements applying to branch circuits.[:-banghead][:-banghead]

Scott's commentary In English 2002 NEC table 210.21(B)(3) and table 210.21(B)(2)

Says it is OK to install 15 amp outlets on a 20 bathroom circuit.[:-graduate]

See what I mean when I say it is not as easy as I would like?

These are the sorts of discussions that scare me. I'm usually busy finding all manner of grotesque major defects in the City that I tend to overlook this sort of detail. Please pass the hairshirt........

Douglas is so correct that I should just study harder & charge more, but sometimes I have to study lots of other stuff instead of minutiae related to a single bathroom circuit. Could someone just say it in a sentence that is 20 words or less so that I can digest it & then move on to trying to understand the current changes to the Chicago Mechanical Code?

[:D]Wow[:D], Having Doug say I did a good job is like having your mentor compliment you.[:-bonc01][:-bouncy][:-bonc01][:-bouncy][:-bonc01][:-bouncy][:-bonc01][:-bouncy]

To bad he doesn't like me bitching about how hard it is to understand[:-banghead]. You would think he helped write it or something.[:-bulb] Oh, That's right he did.[:-censored]

In the last couple of weeks I've been hanging around an NEC code forum (reading only) trying to edjukate myself a little. There are 14,000 plus members, mostly electricians of one sort or another. If the NEC isn't hard to understand then how come there seems to be 14,000 different interpretations of it there?

Me...well I still have trouble with the concept of electricity itself. I drew myself a mind picture a few years back of three elephants turning a windlass attached to a generator. 100 miles away are three elephants spinning around on a carousel powered by an electric motor. Somehow the mechanical power is being transferred from the first group to the second along a thin wire with no moving parts. What's up with that?

You can talk all you want about excited electrons etc but, to someone like me who never approached being a molecular scientist, you might as well be describing how the transporter works on the Enterprise. It’s all just magic and the NEC is a convoluted sorcerer’s manual on how to safely handle the dragon.

BTW…other things I have trouble grasping fully…

Infinity…how can space never end and if it did…what’s beyond that?

The Big Bang theory… actually I have less trouble understanding how the whole universe came from something the size of a football than I do with the question…â€

Thanks Scott; you're a champ. I'll leave interpretations up to those inclined to interpret.

Richard.....

Just remember, infinity is a long way off, & you can't get there from here. It doesn't matter anyway, because if current theories are correct, you're there right now. And there, and there, and there, and there..........
