b.They must not pass through a wall, floor, ceiling, or partition and must be accessible
c.They may be concealed permanently inside a finished wall
d.They are the same thing as CSST distribution tubing
Giải thích
A listed appliance connector is a single, one-piece final connection that must remain accessible and must not be run through walls, floors, ceilings, or partitions. Connectors may not be joined end-to-end or spliced to reach farther. CSST is a distribution piping product with its own rules and is not the same as a short appliance connector.
