Dedicated Space and Working Space. The two distinct spaces within and around electrical equipment with special rules.
Dedicated is above, Working is in front. Agreed, this is one of several areas where there is confusion. You have to do some digging outside of NFPA 13 for the correct answers. Craig L.

Just like many confuse rules for transformer vaults with those for average electrical rooms. Mark A.

Sprinklers are permitted to spray water into the dedicated electrical space as noted, just keep the pipes and sprinklers themselves outside the boundary limits of the space. Craig L.

Sprinklers are not permitted in the dedicated electrical equipment space. What code edition does this change to be allowable per the slide presented? The 2014 NEC allows sprinkler protection for the dedicated space, not specifically that the piping can run in the dedicated space. Please refer to our example diagram in the presentation. The NEC states that the sprinkler protection must comply with the other portions of 110.26(E). This provision is in the 2008 NEC as well. Captain Frank J.
