dpwh steel box sealed shall be sealed with 30-50 penetration asphalt seal or cold applied liquid rubber compound after the concrete had been cured and sawed prior to opening the pavement to traffic. penetration . Metal junction boxes always need to be grounded, whether you're using NM (non-metallic) plastic-sheathed cable or metallic cable. Metallic cable is self-grounding, as long as the cable is properly secured to the box. NM cables are not self-grounding.
