NEC Article 501.15(E) Cable Seals, Class I Division 2
Can anyone suggest a good reference that explains when and where seals in Tray Cable (Type TC) are needed?
For example: Where is the "point of entrance" - when the cable enters a Class I Div 2 Area or where it enters the Explosionproof enclosure in the Class I Div 2 Area?
Thanks;
john
