Romex Height From Floor

One and two family dwellings may use type nm cable section 334 10.

Romex height from floor. Add 2x4 blocks to position boxes away from wide window and door trim. Use letters and symbols to identify boxes. For outlets or line them up with existing boxes to determine electrical outlet height. For switches and 12 in.

8 12 inches from the box depending on the box helps me. Also their is no code in the nec that specifies a limited number of wires in a bored hole. Mark the height from the floor to the center of the boxes usually 48 in. Nm cable also commonly known by the common trade name romex is the most common form of electrical wire nm cable is simply a bundle of individual conducting wires wrapped in a plastic vinyl outer sheathing.

Like it was said their is no code that specifies a height for running romex. If there is no specific code then i can run it at whatever height is easiest for me to drill and easiest to work with hooking up the boxes as long as i put staples to code. Area limits may be increased up to 350 of the table values if open perimeter and automatic sprinkler requirements are met. Height limits may be increased by one story when protected by automatic sprinklers.

Area limits are per floor. Normally the cables carry 10 12 or 14 gauge conducting wires for individual house circuits. That is to say no code in the nec you code perhaps have a state or local code that does specify. I was curious how high you all drill your holes above your receptacles and why.
