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.

Yes, using recycled asphalt millings is an eco-friendly alternative compared to concrete. Millings are reclaimed pieces of gravel that are recycled into aggregate that can be used on driveways, patios, walkways, basketball courts, tennis courts, and more.

Maintaining a driveway depends on the material your driveway is made of. Concrete and asphalt should be sealed to protect against water and freeze-thaw cycles. Cracks and expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. Before you apply a sealant to your driveway, consider pressure washing the surface. It will take off any loose sealant and any grime that might have caused a stain. Sealing over dirt and stains will trap it under the sealer.

If you live in colder climates, consider using sand rather than salt to de-ice. Sand helps melt the snow and ice without speeding up the freezing and unthawing process of your driveway, which helps prevent cracks from forming from the constant fluctuation of temperatures.

Wet cutting is usually the preferred method. It controls dust, which helps protect your lungs and makes for a cleaner working environment. Plus, the water cools the blade, preventing overheating and prolonging its life while providing smoother, more precise cuts. The downside is the mess—water and asphalt sludge can be messy to clean. Dry cutting, though convenient if water isn’t available, creates a lot of dust, which can be harmful. This also increases the risk of blade damage due to overheating. So, if you have the option, wet cutting is the better method for most asphalt jobs.
