TUESDAY 15 November – WEDNESDAY 30 November
As previously noted, the electrical service entrance was prepared on Thursday, November 10. By this time, the weather was changing, becoming cold enough that I could no longer paint. Any painting that remained to be done, such as the outside of the two interior shop/storeroom walls, and the sides of the staircase, would have to wait until spring 2023. With my painting activities curtailed for the winter, and with the electrical service entrance work done, I turned my time and attention to designing the electrical plan for the building using QCAD. Indeed, I started with the building floor plan, turned off details that were not relevant, and added new layers for all of the electrical stuff. Outlets, switches, a sub-panel for the shop/storeroom, and wiring would be fairly straight forward; it was just a matter of how many devices, where they would be placed, and how/where the wires would be run. Lighting, on the other hand, lead me down something of a rabbit hole researching lighting requirements and fixtures.
With a 16’ clearance to the bottom of the roof trusses, I need to use “high bay” light fixtures for the RV bays. These fixtures are much brighter (8,000 to 35,000 lumens) than the typical “shop/utility” tube lights used in many residential garages and workshops (2,000 to 4,500 lumens). Selecting fixtures that will work the way I need them to, required me to jump back into lighting parameters such as illumination (in lumens), color temperature (in degrees Kelvin), Color Rendition Index (CRI), beam patterns and coverage (as a function of height above the working surface), mounting/wiring methods, suitability for use in unconditioned spaces (the RV bays), and energy efficiency. The last one was easy, as all of the lighting that I install will be LED, which has a 10:1 energy advantage over tungsten filament bulbs. (LEDs use ~1/10 the energy of a tungsten light source for the same amount of illumination, or provide 10x the amount of illumination for a given energy consumption.) LEDs also have a lifespan that is 10 to 50 times that of tungsten bulbs, and come in a variety of color temperatures, specifically 5,000 K (Daylight) which is appropriate for areas where work is being done. A comparison to fluorescent lighting would probably be more appropriate, but LEDs still come our way ahead on all of these parameters. I will have more to say on this subject once I have actually selected light sources.
MONDAY 21 November
In spite of the cold weather, and 4” – 5” of snow on the ground, there was work that had to be done. On the couple of occasions when it had snowed prior to today, I used a gasoline powered backpack leaf-blower to remove the snow from the electrical cable paths from the existing utility pole to the house (which had been marked by MISS DIG 811) and the area from the pole to the barn where I intended to dig a trench and install the conduit for the electric service entrance cable.
I had a few errands to run today, and when I returned I found two DTE subcontractor trucks parked in the street in front of our house, with one of them blocking the first driveway entrance. That wasn’t a problem, as the bus is currently parked in front of the house and I had no immediate use for the first entrance. Still, I was curious why they were there so I walked over and talked to the guy in the lead truck.
They had spent the morning working at our neighbor’s house across the street. Our neighbors are the third owners of the first house built in this subdivision. Built in the late 1960’s, the house still had its original 240/120V, 100A electrical service. They are upgrading it to 200A, and that meant a new main panel, a new meter/box, a new transformer, and new cable from the pole to meter. Their existing service was overhead wires from the pole to the house, but DTE will not upgrade those wires. As with new construction (like our barn), they will only run cable underground from the pole/transformer to the meter on the side of building. They also install a terminal strip on the pole a few feet below the transformer and connect the wires from the house and the transformer together at the terminal strip. These particular sub-contractors where an “underground” crew and had spent the morning digging a trench from the pole to the meter location, installing direct-burial cable, leaving enough of it coiled up on a hangar on the pole to reach the terminal strip, and then back-filling the trench. A DTE crew will come out and remove the old overhead cable and transformer, mount the new transformer and terminal strip, route the new cable up the pole, and make all of the connections.
The sub-contractors were on a break, and I asked if the guy would be willing to take a few minutes to look at my situation. The thing that has been a source of confusion for me was where to end the trench/conduit, and what direction it should be pointed. My DTE planning consultant had simply indicated “about 10’ from the existing pole.” But that lacked the specificity that I wanted as we were (apparently) also getting a new/taller utility pole that would (probably) be installed “about 5’ to either side of the existing pole.” It would, of course, be in line with the existing overhead cables (power, broadband, and phone). I knew that DTE would also install a ground mounted junction box/pedestal and that the wires from the house, barn, and transformer would be joined in this box. But it was not clear exactly where the pedestal would be placed relative to the existing pole, much less the new pole in an as yet undetermined location. My confusion/concern was also partly fueled by not having ever dealt with this before and not understanding exactly what was actually going to happen.
The sub-contractor looked at my proposed path and filled in a few critical pieces of missing information. I learned that the junction box would (likely) be installed about 3’ from the new pole, directly away from the edge of the driveway. If I located the end of the conduit in-line with a line offset from the existing pole by 3’, and stopped a few feet short of the possible closer junction box location, it would be a perfect setup for a crew (like his) to do what they need to do. I also learned that they will NOT install additional conduit from my conduit to the junction box; all the cable they use is rated for “direct-burial” and does not actually require conduit. (Conduit is nice, however, especially in rocky soil or other situations where it might be subject to damage.) They will simply trench from the end of my conduit to the junction box/pedestal location, as well as from the pedestal location to the new pole location. Finally, he assured me that I would not have any difficult bending the 2” Schedule 40 conduit along my indicated path. Based on what I learned, I staked out the actual path for the trench/conduit from the barn to near the existing utility pole, using landscape flags.
TUESDAY 22 November
Today was spent digging a trench and installing approximately 90 feet of 2” Schedule 40 PVC electrical conduit, including a 36” radius sweep (quarter circle) and a 12” long 22.5 deg elbow. The conduit will house the service entrance cables that the power company will run from the pole to the building.
My friend and fellow converted bus owner, Marty, who is a licensed electrician, agreed to come over and help with this task. I was glad to have the help. The work proved to be quite physical, and often required coordinated effort; I doubt that I could have accomplished it by myself. Linda also helped, off and on throughout the day, taking breaks from her accounting work to take photos, fetch things that we needed from the garage, fixing a light lunch, and taking on the task of cleaning the rented trencher with our power washer once we were done digging. (We had chosen this day to do the work because the high temperature was going to be well up in to the 40’s.)
But before that happened, I used yellow marker paint (spray can designed to work when inverted) and “painted” the path that I had marked with flags yesterday. I then unloaded the 36” trencher from the trailer as I wanted to be ready to work as soon as Marty arrived around 9 AM.
I did not get a photo of the control panel, but it consisted of a choke and throttle for the engine, a control lever to lower/raise the blade, two drive controls for the left and right drive treads (like a bulldozer), and a lever to engage/disengage the chain. The engagement lever moved sideways, and had to be pulled over with my right hand and held there while also operating the right drive tread. It was actually easier than it sounds, and I got the hang of operating this beast fairly quickly.
WEDNESDAY 23 November to MONDAY 28 November
I was sick with an upper respiratory viral infection during this time (and beyond), and nothing else much was accomplished on the barn. I did learn on Monday that the ETA for the two large roll-up doors is now December 28 (of this year). I also emailed our DTE planning consultant to let him know the conduit was installed in the trench and included pictures, as requested. He indicated that he would (finally) do our plan/quote on Monday, November 28. On Monday, I also heard from Phil at Precision Grading that he would have the 21aa stone delivered tomorrow and be on site to finish the west pull-through driveway extension to the barn.
TUESDAY 29 November
Phil arrived around 10 AM. He got his front-loader and bulldozer unloaded from his equipment trailer and then unloaded a large roll of road/construction fabric from the box of his dump truck using forks on the front-loader. I made myself available to help with placing the road/construction fabric, but otherwise spent most of the day cleaning up the dirt along both sides of the conduit trench. This included gathering up medium-to-large rocks and using them as fill for the somewhat larger hole near the meter and along the first 5’ of the trench. I took occasional breaks to take photos of the driveway work. We both finished up around 4:30 PM. It was a long, hard day, but a lot got accomplished.
Buy the end of the day, the new driveway extension was a surface that could be driven on comfortably, but was not as compacted as I wanted it to be. In the next few days, I would use the F-150 to drive back and worth over the gravel from a variety of directions to pack the surface, but that’s for a future post.
WEDNESDAY 30 November
One of the carpenters from Patriot Builders was here today to install the locking door knobs and deadbolts for the entry, shop, and storeroom doors. The three door knobs and two deadbolts (shop and storeroom) were all keyed alike.
