Pole embedment depth is typically calculated as what?

Pole embedment depth is chosen to ensure the pole stays stable under load, combining a proportional bury depth with a practical minimum. The depth that uses 10% of the pole length plus 0.6 m provides that balance: the 10% scales with how long the pole is, so longer poles go deeper to resist overturning, while the fixed 0.6 m (about 2 ft) guarantees a minimum burial to handle soil conditions and frost, even for shorter poles. This makes the depth consistent across different pole lengths. The other options either miss the fixed minimum or use a percentage that would not give reliable embedment for all pole lengths, leading to under- or over-embedment.
