Safety
when testing wires:
Never touch wet or previously flooded appliance. Never stand on wet surface when working on electric. Never stand on bare soil, put down dry boards. Tape tester leads to wood sticks to keep hands away from power. Use non-contact voltage tester before touching wires. Never touch or lean into any made of metal. Remove metal objects from pockets. Do not use oxygen or fuel accelerants in same room as electrical repairs Resource: Basic house wiring |

 Electrical tools must be insulated. Always best to disconnect power, but insulation failure, lack of proper grounding, grounded neutral, lack of GFCI, out-of-code wiring, generator operating without transfer switch, and other problems still pose a risk to anyone working on electric power ... even when breaker is off.

Old
work box is installed in hollow part of wall Can be installed on any interior wall Do not locate where pipes, other wires, or pocket doors are present. Wire is dropped into wall, and then hole is cut for box. Do not cut hole for box before dropping wire.  Buy: Old work box at Amazon Wire wire at Amazon Resource: Select wire and breaker size |

Instructions:
Drop wire from attic before cutting hole for box. Once wire is dropped down inside wall, have helper rattle wire around. Noise from wire will confirm location to cut hole. Helper pulls wire up out of way so saw will not cut wire. Cut 2-1/4" x 3-3/4" hole in sheetrock using knife or saw Reach in and find electric wire inside wall Pull electric wire through hole Feed wire into box Set box into hole Turn screws so pop-up fin tightens against inside of sheetrock Install switch. Note: Water Heater Timer requires only one box and one wire. |
 |
Instructions for locating where
to drop wire: 1.Before going in attic, choose wall for switch 2. Avoid walls with pocket door or plumbing pipes or exterior walls with insulation 3. Go in attic and estimate location of wall Wear protective mask around insulation 4. Pull back insulation & find top plate as shown. 5. Each interior wall will have double 2x4 top plate that will be visible when insulation pulled back. 6. Have helper tap on wall from below 7. Note location of other wires. Do not use drill next to other wires or damage to wire can occur accidently. |
 |
If
another wire already drops through top plate where you want your
wire, see if your wire will push through same hole. If you have to drill, move over several inches from other wires so drill won't contact wires. When drilling through top plate 3 things may occur: 1.) You may hit a nail > drill another hole 2.) You may hit top of upright 2x4 > drill another hole 3.) You may drill into the wrong cavity > that's why you drill through top plate before cutting hole in sheetrock Tip: after drilling hole in top plate - and - before cutting hole in sheetrock, drop your wire into wall and have helper rattle it around to make sure you're in the right spot. Put timer at eye-level so it's easy to program. |

Cut-away view of
residential wall 1) Drop wire through top plate. 2) Have helper rattle wire inside wall 3) Noise from rattling wire will identify where to cut hole for box 4) Try to identify mid-way between studs so blade will not cut existing wires. 5) Existing wires will be stapled onto 2x4's Do not cut wire accidently Buy Tools DEWALT Black and Decker Stanley SKIL Makita Porter-Cable Bosch |
 |
Other
wires can
be inside same wall 1) By code, other wires are stapled to 2x4's 2) However, not every home has code wiring 3) Existing switches and outlet boxes will be attached to 2x4 4) Wires also run horizontal through walls 5) Horizontal wires usually located below level of outlet box ... BUT can be anywhere inside a non-code structure Be careful When cutting through wall to install old work box: Do not put blade far inside wall where it can hit other wires and possible pipes Use a utility knife to cut hole Cut hole slowly Locate old work box in center between 2x4s Buy deep scan stud finder: Deep scan stud finders at Amazon |
