Services are limited to 200 feet because of voltage drop. Generally, the longer the service, the more your lights will flicker when various loads start in your home. It is not possible to eliminate flicker entirely, but 200 feet, with the common loads we see in this area, is a good balance between flickering lights and cost/convenience. Some utilities limit their secondary service length to 100 feet. Shorter lengths are many times required where there are large air conditioning and compressor loads.
