Multiple tenant store front signs on one circuit?

I think it is time to post the relevant NEC code sections, as always local or other codes may have an impact as well.

210.62 Show Windows. At least one receptacle outlet
shall be installed within 450 mm (18 in.) of the top of a
show window for each 3.7 linear m (12 linear ft) or major
fraction thereof of show window area measured horizontally
at its maximum width.

The above section has to do with interior receptacle outlets and has nothing to do with exterior signs.

600.5 Branch Circuits.
(A) Required Branch Circuit. Each commercial building
and each commercial occupancy accessible to pedestrians
shall be provided with at least one outlet in an accessible
location at each entrance to each tenant space for sign or
outline lighting system use. The outlet(s) shall be supplied
by a branch circuit rated at least 20 amperes that supplies
no other load. Service hallways or corridors shall not be
considered accessible to pedestrians.

Now this section requires a sign outlet at each entrance but it does not require that it be used.

Thak you for posting the code! Much appreciated.

It's a bit pedantic, but not every pane of glass is a 'show window.' Nor is it specified if the accessible outlet be inside or outside the entrance. Examples of windows that are not 'show windows' could include the pane of glass next to a glass door (as at the local 7-11), and the glass front of many mall stores, where the area 'inside' the glass is the retail floor (with no platform for displays, etc.).

Nor, as you pointed out, is it required that every sign use that particular outlet.

Again, being pedantic, I remind all that an 'outlet' need not be a receptacle.

I suppose one could also discuss whether, in many cases, some signs are 'accessible.' I daresay that very few are 'readily' accessible, but that's not an issue here.

For the show window a receptacle is required, for the sign circuit only an outlet is required.
