In this case you need to create two floor plans one showing where the various switches and receptacles will be located in the.
Receptacle 16 from floor where should romex run.
It also must run within 12 inches of each metal box or within 8 inches of each nonmetallic box.
X post from r electrical i am installing two receptacles on the floor of my second story den and i want to know the proper way to run the romex from the wall to the new outlets.
Use letters and symbols to identify boxes.
For switches and 12 in.
Anytime i see exposed romex wiring in a garage that is lower than 7 i call it out even though when structure was constructed it may have passed inspection.
The floor joists are approximately 9 or so above the floor.
3 run the cable through the holes you drilled in the studs or joists toward the new receptacle box taking care not to kink or twist the cable.
Some of the parallel runs are along the bottom edge some are along the vertical side of a joist.
For outlets or line them up with existing boxes to determine electrical outlet height.
Mark the height from the floor to the center of the boxes usually 48 in.
Smaller cables shall be run either through bored holes in joists or on running boards.
Begin with a plan.
Securing cable in new construction cable must be stapled or supported with straps every 4 1 2 feet.
Running romex for floor receptacle under second story osb subfloor.
Where passing through a floor the cable shall be enclosed in rigid metal conduit intermediate metal conduit electrical metallic tubing schedule 80 pvc conduit or other approved means extending at least 150 mm 6 in above the floor.
You should begin every project with a plan.
On the first floor run wires up the wall from the basement.
Add 2x4 blocks to position boxes away from wide window and door trim.
Cable is run at angles with joists in unfinished basements and crawl spaces it shall be permissible to secure cables not smaller than two 6 awg or three 8 awg conductors directly to the lower edges of the joists.
When necessary use existing ducts or pipe runs to get wires from the attic into the basement.
On the second floor run wires down the wall from the attic.
However tying the wiring into the service panel circuit breaker box and thus electrifying the wire can be an uncomfortable task for many amateur electricians.
At this residence romex 10 2 12 2 14 2 can be found stapled to the floor joists in virtually every direction parallel perpendicular and across at angles.
