gases

Selection
Refer to page headings for suitability of specific items. When selecting a Killark
device consider the following:
(A) Installation area (Hazardous or Weather-Resistant)
(B) Amperage
(C) Voltage
(D) Electrical Rating (see below)
(E) Grounding
(G) Modifications (see right)
(H) Mounting arrangement
(I) Box and hub type
(J) Cord diameter

Details of Safety
Time Delay Feature

The key slot provided in the receptacle engages the key of the plug permitting
entrance of the plug in the receptacle in only one position. See steps 1-4.
The contacts are enclosed in long accurate insulating cavities. It is in
these cavities that the arcs are extinguished.
All contacts are made through round tellurium copper tubing which is extra heavy to withstand arcing as required on the various ampere ratings.
Both plugs and receptacles are equipped with an extra long grounding
pole which establishes grounding before the power contacts are engaged. These grounding poles are also the last to break contact. This assures bonding of the portable device to the electrical conduit system.


Selection
Modifications are available by adding the following suffix to the catalog number.
(Note: It must be added to both the plug and the receptacle so they will mate.)
