San Francisco Electrical Codes, as you can expect, follow the California Title 24 rule as well. By following California’s electrical codes, San Francisco in turn follows the NEC.
There is one major difference in the city’s electrical codes from the state level.
As stated in Article 356 of the San Francisco Electrical Codes, “LFNC [Liquid Flexible Nonmetallic Conduit] shall be permitted to be used in exposed or concealed locations for systems not exceeding 50 volts.” In simpler terms, this means that the power infeed to a modular power distribution system must be inside metallic sealtite.
While that is limiting in some respects, the up side is that it’s the only unusual requirement.
In San Francisco, corded power and data units are acceptable to be plugged into a modular power distribution system, as long as the power infeed to the modular power distribution system is metallic sealtite. This allows for easier design and construction of modular furniture and systems with electrical capabilities.
Corded units also add the benefit of being easily transported. For example, in situations such as classrooms where furniture may be moved from year to year (or even on a class-dependent basis), it’s far easier to unplug and rearrange furniture as necessary. Your only limitation is the length of the cord rather than the original construction of the room and outlet dependency.
This also makes open workspaces much easier to design and plan around. As an office grows and new workstations are added, it’s simpler to add corded power and data accessories rather than to plan around hardwiring layouts.
Largely because they’re easier to design and configure spaces around, corded power and data accessories are also far simpler to find. So, not only are they easier to use in design, but they are also easier to find in your exact preference.
In San Francisco, the sky’s the limit… As long as you’re following all other California Electrical Codes, including the lighting and receptacle codes as detailed in this blog.
