If CA follows NFPA 70 without any kinds of modifications or amendments, there is no restriction on the routing of a sprinkler line through an electrical room as long as you are outside the Working Space and the Dedicated Electrical Space as defined with NFPA 70, 110.26. The sprinkler line does not have to serve only the electrical room as some believe. See 110.26 (E) (1) (c).
One thing to note about electrical rooms is that if the electrical gear is oil filled, it's not going to be an ordinary hazard occupancy any more, sidewall goes away as an option. Be sure you know if the electrical gear is dry or oil filled. Craig L.

We've been following NEC 110.26 (f) (2008). Has there been a change to the electrical code / CBC requiring this? Jerry Van Kolken Millennium Fire Protection Corp. 2950 San Luis Rey Rd.
