Depending on the install, any of the above could be correct (speaking on the initial poll).

Like I said, someone could op for NEC 250.64

And per e57's note of this question being for a GEC, (read the last sentence of the OP)250.64 would be the applicable article section.

But #8 is the smallest of the choices so it would be the minimum size.

That's what I selected--yet posted in the begin, that many may op for 250.64.


Roger,
Thanks! I think! Or read post 6 and 7

Post 6 and 7 doesn't change the OP or the correct answer. ;)

I'm not following what 430.21 has to do with the question, though.

The question makes no distinction about the use or purpose of the conductors - 310.16 doesn't apply to motor control conductors... The correct answer would be 30A via 240.4D
Small Conductors. Unless specifically permitted in 240.4(E) through (G), the overcurrent protection shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG copper; or 15 amperes for 12 AWG and 25 amperes for 10 AWG aluminum and copper-clad aluminum after any correction factors for ambient temperature and number of conductors have been applied.

But the question says nothing about the use of the conductor.... Table 240.4(G) has a list of other codes where 30a could be exceeded.

Nor does it mention copper or aluminum...

Sorry I really should re-read before I post but get nailed by that can edit message all the time.... Diarea of the keyboard - I'll admit it.... :roll:

I'd say the correct answer is 30, simply because 40 is not listed in T310.16, but 35 is. But since 35 is not a choice, then the answer is 30. If you listed 1 amp, 2 amps, 3 amps, and 5 amps, then the answer would be 5 amps.

If the question states no other information that may take you to T240.4(G), then 30 would be the answer. But you're providing some information that may invoke T240.4(G).


Copper is the required choice then. 110.5.

I would disagree - I still say #4 as there in no qualifier for the interpetation of damage..... As the code says in the next portion of the same sentance, "otherwise, it shall be in rigid metal conduit, intermediate metal conduit, rigid nonmetallic conduit, electrical metallic tubing, or cable armor."

Ironicaly local interpetion is that any exposed GEC is subject to physical damage, and any exposed to the street is subject to severe physical damage.... Copper thieves....

Whatever, but the bottom line is your answer is wrong because you are trying to answer a question that was not asked. (looking for a qualifier that is not necessary to the question)

From my OP... Exactly my point!
Dare I say it - being so used to debate about codes here I may have shot myself in the foot and came in second

I'm getting too used to desecting and digging deeper.... ;) Looking for the 'what if's'...
