In remodeling my kitchen, I'm adding new outlets on circuits where the existing outlets are at floor level (bottom of the outlet is 9" above the floor, to be exact). In one particular case, I need to keep the outlet at floor level for the fridge and run a new outlet (daisy chained from the floor level fridge outlet) to counter level. Is it OK to do this vertical or perhaps slightly diagonal run (< 4 1/2 feet) of romex in the finished wall without providing any additional support between the two outlets?
If not, what would you suggest with minimal disruption to the finished wall? I do have access to the floor from the basement and ceiling from the attic.
I read 334.30 to OK this practice, but I don't know all the ins and outs, being a DIYer.
334.30 Securing and Supporting. Nonmetallic-sheathed cable shall be secured by staples, cable ties, straps, hangers, or similar fittings designed and installed so as not to damage the cable at intervals not exceeding 1.4 m (41⁄2 ft) and within 300 mm (12 in.) of every cabinet, box, or fitting. Flat cables shall not be stapled on edge.
(B) Unsupported Cables. Nonmetallic-sheathed cable shall be permitted to be unsupported where the cable:
(1) Is fished between access points, where concealed in finished buildings or finished panels for prefabricated buildings and supporting is impracticable
(2) Is not more than 1.4 m (41⁄2 ft) from the last point of support for connections within an accessible ceiling to luminaire(s) [lighting fixture(s)] or equipment
