Drake,
It seems the code is providing some flexibility for the location of OCPD in
battery circuits. Placement "as close as practicable to the storage battery
terminals" is ok even if that is in an enclosed space (say a battery box) where
the possible accumulation of flammable gases may occur.

Hello Wrenches,

I'm studying the NEC for a rectification exam, and came across this 
little gem. Can anyone explain what the following code rule is saying 
from 240.21 H, (Overcurrent Protection, Location in the circuit)?

(H) Battery Conductors. Overcurrent protection shall be
permitted to be installed as close as practicable to the storage
battery terminals in an unclassified location. Installation of the
overcurrent protection within a hazardous (classified) location
shall also be permitted.

It seems to say we can't do something, but we can anyway. The 
Handbook provides no clarification.

Thanks,

Drake
