Burying cables: what are the regulations for buried cables? | NAPIT
The one figure that we all agree on as an industry, is that any buried cable should be at a minimum depth of 0.5 m, where a special location requirement does not cover it. This is because with light hand digging, such as in a garden, etc., we may subject a cable (even an armoured one) to damage at depths of less than 0.5 m.
