Box fill refers to the maximum number of conductors that can be contained within a wiring enclosure box, as well as the total volume of the components. Determining the allowable number of conductors in a box requires adding up the number of conductors, clamps, support fittings, devices and equipment, and equipment grounding conductors to make sure you’re within the allowable volume.

The dimensions of a driveway apron vary based on local building codes, the width of your driveway, and the distance between the driveway and the road. On average, aprons range from 12 to 24 feet wide and 8 to 18 feet long. Typically, the end of the apron connected to the driveway matches its width—such as 10 to 12 feet for a single-car driveway—while the end at the street flares out to allow cars to turn in and out more easily. In some areas, you may not be responsible for the portion of the apron that extends beyond the sidewalk, but this depends on local laws.

Many asphalt companies have experience with tar and chip paving, but not all. The process is unique enough—and not incredibly common enough—that you may have to look around for a tar and chip specialist. However, speaking with a driveway company is a great place to start, especially if they have experience with multiple materials.

There’s no single best asphalt grade—it all comes down to where and how it’s used. Highways and heavy-traffic roads need something tough, like polymer-modified asphalt (PMA) or Stone Matrix Asphalt (SMA). Local roads and parking lots rely on the Performance Graded (PG) system, chosen based on climate. A PG 64-28 mix, for example, handles a broad temperature range while simpler, more cost-effective mixes are typically enough for residential driveways. The best grade of asphalt depends on traffic, weather, and your budget, which is why a professional’s input is always a smart move before making a decision.
