Electrical wiring for a new log home is always a thing that worries owners. As wood is organic it can easily get burned and so a perfect kind of electrical wiring is needed for a material like wood. The electrician performs his main task once the dry-in phase of construction is complete. The electrician should be contracted and he also should be consulted early in the construction process to approve and supervise wiring in the second floor system, roof system, and in the log wall system. All the wiring practices are to be approved by and supervised by your electrician.
In order to wire the outlet boxes many holes would be needed and so they should be drilled and this is to be done when your log erection crew is installing the logs and not later than that. The construction crew will want to mark the location of the holes when they drill these holes on the sub floor. You need to make sure the drilled holes go all the way through the sub floor. The outlet box holes are to be cut then.
A very good way to notch out an outlet box is something you should know about. That is to mark the outline of the box on the log wall, using the actual box as the pattern. Then you would need to drill a series of 1-inch to 1-1/2-inch holes within the perimeter of that outline using a butterfly bit or hole-saw bit. Cleaning the holes is to be done with a chisel. Then plunge the wiring hole to remove chips and sawdust with a stiff piece of wire. The dry in process is to see the holes being drilled and the outlet boxes being cut.
The wires need to be drilled through the rafter or rather the ridge beam when it comes to light fixtures and these wires should hang directly underneath the rafter. A block of wood is needed for rafters that run at an angle to mount to the bottom of the rafter. Even this block is to be cut at the angle of the roof pitch. This is done in order to create a bottom flat surface that is level with the house floor. At the bottom of the block is where the light should be mounted.
When it comes to the wiring for cable and phone lines as well as burglar alarms and so on you would need to consider the process of the wiring before and throughout the construction process and wiring runs coordinated with your electrician. All this wiring is normally run under the sub floor with legs branching upwards at windows or the doors, stud walls etc.
Wiring to overhead lights under a the roof system can run from under the sub floor, up through exterior door jambs and for that you would need to drill through logs above doorway, or interior stud walls, or over the top of the roof decking to the proper location, then down through drilled holes to the light fixture location.
