| They installed conduit in the walls of the entry room because those walls will be covered with brick. | |||
 |
 |
 |
 |
| Conduit was installed in the interior walls to provide future access. | An electric rigid hot knife was set to the proper depth, then pulled though the ICF to create the channels for the conduit. | The top and bottom edges of the black plastic inserts were cut with a reciprocating saw, then they were knocked out of the way with a claw of a hammer. | |
 |
 |
 |
 |
| Cliff Gore drilled a hole into the metal brick box and then into the concrete wall with a power hammer, then screwed 1/4" x 2 3/4" Tapcons to secure the box the wall. | Cliff heated the 3/4" PVC conduit so that it could be bent. | ||
 |
 |
 |
 |
| After rechecking the length, Cliff cut it. He then slid a PVC male adapter through the knocked out hole of the box, added a plastic bushing, then secured it with a metal lock ring. The conduit was then glued to it. | John Weatherly used a larger hammer drill to penetrate the corner of the 6" concrete wall. | The conduit was secured to the wall with one hole metal straps every 10'. The wire will be inserted later, after the brick work. | |
| The rest of the house was wired with 12 AWG Romex and MC cable. Channels were cut into the ICF with a hot knife, but the plastic strips were left in place. A drill with a flexible shaft was used to remove the foam from the back of the plastic strips to allow the wire to pass through. The strips kept the horizontally run wire in place. | ||

 |
| Mark Borch-Jensen screwed the boxes to the concrete with 1 1/4" x 1/4" Tapcon screws. | Mark and Tom Bos then pulled the Romex wire though the back of the plastic strips of the ICF block. | The Romex and MC cable and phone cable were run to the boxes, secured to the wall and boxes, then raised covers were screwed to the square 2 1/8" boxes. |
| Metallic sheathed MC (Metal Conduit) cable was used with the steel framing because Romex might rub and split against the sharp metal edges. | ||||
 |
 |
 |
 |
 |
| These MC connectors secured the wire to the electric boxes. |
The end of the outside of the cable was cut off with an MC splitter. |
Metallic 4-square 1 1/8" deep boxes were screwed to the metal ceiling joists, the wire was secured to the box with the MC connectors, the green ground wire was screwed to the box, then a raised cover was attached. |

 |
 |
 |
 |
 |
| Tom lubricated the bit so that it effectively drilled a hole into the 18 gauge steel track. | The center of the hole was removed, then MC cable was pushed through the hole for a ceiling light. | |||
 |
 |
 |
 |
| The ends of the cable were removed with an MC Splitter, the wire was secured to the box, then the ground was attached to the box. | Mark drilled holes for the wire because the holes in the steel studs did not line up. | ||
 |
 |
 |
 |
 |
| John fixed the span of the light can supports by cutting and adjusting them to fit between the joists before screwing them in place. |
He then centered the can and screwed it in place. |
Then he removed the protective sheath from the ends with wire strippers, joined like-colored wires, then twisted on wire nuts to secure the connection. | ||

 |
| Kelly McCully drilled a hole for the wire to enter the house. | Mike and Kelly installed the exterior electrical box for 600 amp service. | On the inside, Tom separated the neutral (white), ground (green), and hot wires, then screwed them in place. | Then a metal cover was screwed into place. |

Steve Vaughn pushed through wire |

 |
| The 600 amp service was connected to the main box as two lines encased in flexible conduit 30" below ground level. The ditch was dug deeper where it crossed a water line because it had to be 12" below the water line. After the wires were in place and the conduits were glued together, they were covered with 12" of dirt, then wide red plastic tape was run over them as a warning to future excavators, the phone cable was placed in the ditch, then the ditch was filled. The black phone cable (from the green box on the right) had to be 12" away from the electric line so it ran around the pole, before being placed a foot above the conduits. | |||
