Clamps

DOE-SPEC-3021-97

Clamps. Clamps used other than in bundles (see

3.3.11.6

paragraph 3.3.12.2) shall be spaced uniformly at distances no

greater than 24 inches apart.

3.3.11.7

Terminal boards. Provide terminal boards for all controls,

instruments, annunciators, meters, and relays requiring external

cable connections.

Terminations. Seller's wiring shall be terminated on

3.3.11.7.1

terminal boards or equipment with

insulation-gripping insulated wire terminal lugs.

3.3.11.7.2

Lugs. The tongue portion of the terminal lugs shall

be [ring-type].

3.3.11.7.3

Tools. Use ratchet-type tools when attaching lugs to

wires, to avoid loose connections due to insufficient

pressure while crimping.

Clamps. Box-clamp or saddle-clamp terminals are

3.3.11.7.4

not acceptable because of possible damage to wire

ends. Provide relays and other devices without

saddle clamps or remove the clamps in panel

assembly and use ring-type lugs for panel wiring

these devices.

3.3.11.7.5

Terminal types. No solder or "push-on" or "quick"

type terminals shall be used except:

a. Solder-type for pushbuttons, or indicating lights,

when specified

b. Solder-type for flat resistors when specified

c. Push-on for indicating lights when specified.

External connections. Owner's external connections

3.3.11.7.6

will be via cables with [12, 14, 16] AWG, stranded

copper conductors and lugs similar to those

described above. Terminals for the Owner's

external connections shall be arranged for

consecutive connection of conductors within one

cable. One external wire shall be connected to each

outgoing terminal point.

Internal wiring. In Seller's internal wiring, not more

3.3.11.7.7

than two wires shall be connected to one terminal

block point. Not more than one wire shall be in any

terminal lug. (Individual termination in each lug is

necessary, to facilitate trouble-shooting.)
