How much gravel is required for hand holes?

Gravel fill in hand holes provides drainage and cushioning for the cables and splices inside, helping to prevent water buildup and pressure from shifting soils. The standard depth specified is four inches. This amount delivers enough drainage and a stable base without adding unnecessary height or cost. Using less, like two inches, risks poor drainage and inadequate protection of the conduits. Using more, such as six or eight inches, is typically unnecessary and can complicate installation and increase material cost. Use clean, washed gravel and spread it evenly so water can flow away from the hand hole and the cables remain well protected.
