My wife and I live in a ten year old neighborhood where all our utilities are underground. Unfortunately the transmission feeder lines are above ground and can be affected by severe weather or other calamity. After experiencing a six-day power outage in Northern Virginia after the June 2012 Derecho and another 12 hour outage in May 2014, where in both cases we lost our refrigerator and garage freezer contents, we had had enough. We needed an automatic generator system so that when we were not at home—like the during the May 2014 incident—we would not have to worry about our refrigerator/freezer, sump pump not operating or comfort of our pet. In June 2014 we had a 20KW Generac generator installed by Vancelectric LLC, Annadale, VA. The installation required a week after they started—excluding the time for Washington Gas to increase the meter size (completed within two weeks from request—it was summer).
Vance Cowper’s crew was polite and professional. As an example, during the few times that they needed access to the interior of the house or power needed to be off, they gave my wife advance notification, a time that she could expect, and kept to the schedule. They put down mats to protect the basement carpet during rewiring of the panel boxes. The crew was very nice. Once the job was complete and given final inspected by the county, Vance demonstrated the operation by simulating a power outage. This evaluation has been in the draft stage for months. I have delayed in posting this write up until my system was exercised during a real power outage. As it happened, October 16, 2014, at 3:19am I experienced my first ‘real world’ operational test. When I woke at 6:00am to get ready for work, I noticed my entire neighborhood was dark except for my house. After seven hours, power was restored and the generator went back to standby mode. I probably turned on a few more lights than I needed that morning just to show off! I purchased and would recommend the wireless monitoring device that sends messages to my email and smart phone application for any change in the generator status. I was at work when I received a status update that the generator went back to standby mode. Everything worked at advertised. I am very pleased.
How did I choose? First, I wanted a U.S. made generator and it would take too long to explain why Generac; I am convinced they are the best. I considered two independent installers and a leading hardware chain. I was looking for a company that would install as well as service and maintain my generator. I read some Generac installers will only do warranty service on those generators they installed—caused in part on the level of Generac’s remuneration for warranty work. I was confident that Vance Cowper was giving me the best priced solution for my situation: he was a certified Generac Generator installer; took time to adequately answer all of my detailed questions; would provide service and maintenance; had generators in stock; and his company’s on-line posted past performance was excellent. I eliminated the hardware chain as an option since they use a subcontractor for my area to install their Generac Generators. Based on comments gleaned from on-line forums concerning servicing, it seemed to me the subcontractor had a history of getting overwhelmed during major environmental events that would affect their emergency response time. The other independent contractor was approximately three thousand dollars more in price and did not demonstrate the breadth of knowledge that Vance had.
The details. My house’s space and water heating, stove are natural gas, our double oven is electric (max with both ovens on is 40 amps/240V), and we have three external air conditioning compressor units (40, 30 and 20 max surge amps/ 240V) (the smallest unit is a heat pump as well during winter). The house has a total of 66 branch circuits that are mostly lighting. The house originally came with two side by side individual 200 amp/240V service entry panels in my basement fed by two individual cables from the outside meter panel. The generator installation site is situated five feet from the side of the house near the power meter, within 10’ from the natural gas meter and 6’ and 12’ to the two larger air conditioner compressor units. This location is probably ideal for this kind of installation since all utilities were fairly close at hand and load shedding wiring of the air conditioners was minimal. The gas meter was changed by the gas company to support the generator two weeks prior—Vance took care of the details to make this happen. While I do not specialize in power systems, I have two degrees (BS and MS) in Electrical Engineering and have a ‘fundamental’ understanding when it comes to power transmission and home electrical systems. When I started my technical discussions with Vance, I explained my background, told him I am smart enough to be ‘dangerous’ (I know my limitations) and had several questions. He smiled and proceeded to field all my questions and remarks with the greatest of patience (e.g. permitting and inspection process, size of cables, wiring of the current panel boxes to sub panel configuration, depth of buried wires, wire gauge, and gas pipes, schedule, etc. . . .). I do admit engineers have to know everything! I concluded Vance knows what he is doing. During my research I even suggested to him my own design of using a Generac 20kW Air-Cooled Generator with one 400 amp Generac Smart Switch, Service Rated switch box to interface between the generator, the meter panel and my existing two 200 amp panels. My logic was I had two 200 amp panels so the switch had handle a least the 400 amp load. Yes, he agreed it would probably be compliant. Vance said he could easily use the 400 amp switch, if I wanted. However, Vance countered, it would be less expensive by approximately $1000 (he actually gave me two proposals), if I agreed to two 200 amp Generac Smart Switch, Service Rated switch boxes, connected to the generator through a 12”x12” junction box situated right below the two switches. He explained that one of the switch boxes could still be wired to ‘load shed’ the two air conditioners, if by remote chance the two compressors turned on simultaneously and the motor start up current caused an excessive draw with the remaining house load. He stated his team had done this type of installation several times, and it met code. The result is all of my house branch circuits are active during a power outage. The likelihood of exceeding the 20KW rated 90 amps/240V during an outage is minimal under this configuration. I selected Vance’s suggested two switch box design with the generator sitting on a GenPad 3” pre-made pad. I opted for the Mobile Link Standby Generator Wireless Remote Monitor device that used cellular telephone system for communicating status to your email or smart phone application. So much for my expertise—at least I ultimately selected the generator kW size correctly!
I should mention during installation, I would come home from work at lunch and early some days just to watch them work. The crew was very gracious and answered every one of my “how come” questions. I took pictures and it was fun to watch them work. I must have been a pest.
