and equipment, prior to it being placed into active
service (CMP-13)”. This seems to go beyond installing
and testing to ensure the system works. On more
complex systems commissioning is often done with a
manufacturers rep, the installer and the facility manager.
The facility manager typically learns proper use of the
system. All this is good practice, but all this hand-holding
takes time, and time is money. Installers will need to take
this into consideration when bidding these jobs.
Lastly, I can see this requirement expanding into
dierent electrical systems as the electrical industry
gets increasingly more technical and complex.

connector and at intervals not to exceed 7.6 m (25 ft).
(C) Separation of Circuits. Class 2 emergency circuits shall
be wired in a listed, jacketed cable or with one of the wiring
