2023 NEC Article 805-840

If the building or structure served has no intersystem bonding termination, the bonding conductor or grounding electrode conductor shall be connected to the nearest accessible location in one of the following EXCEPT: 810.21(F)(2)

Antenna conductors for transmitting stations, attached to buildings, shall be firmly mounted clear of the surface of the building on nonabsorbent insulating supports _______ (810.54)

What is a device that converts a broadband signal into component voice, audio, video, data, and interactive services signals and provides isolation between the network power and the premises signal circuits? (830.1)

A network-powered broadband communications circuit located outside and entering buildings that is installed using Type BMU, Type BM, or Type BMR network-powered broadband communications, is what type of circuit? (830.40(A))

A network-powered broadband communications circuit located outside and entering buildings shall be installed using Type BLU or Type BLX network-powered broadband communications cables, is what type of circuit? (830.40(B))

What is the minimum distance of overhead (aerial) spans of network-powered broadband communications cables when above finished grade, sidewalks, or from any platform? (830.44(B))

Final spans of network-powered broadband communications cables without an outer jacket shall be permitted to be attached to the building, but they shall be kept not less than                   from windows that are designed to be opened, doors, porches, balconies, ladders, stairs, fire escapes, or similar locations. (830.44(D))

Network-powered broadband communications cables on buildings shall be installed so that there will be no unnecessary interference in the maintenance of the separate systems. In no case shall the conductors, cables, messenger strand, or equipment of one system cause abrasion to the conductors, cables, messenger strand, or equipment of any other system. (830.44(F)(2))

Primary electrical protection shall be provided on all aerial or underground network-powered broadband communications conductors that are neither grounded nor interrupted and are located within the block containing the building served so as to be exposed to lightning or accidental contact with electric light or power conductors operating at over           to ground. (830.90(A))

When power fault currents on all protected conductors in the cable are safely limited to a value no greater than the current-carrying capacity of the primary protector and of the primary protector bonding conductor for grounding electrode conductor, what primary protector are permitted?
