CORD, SWITCHBOARD


These include the flex, cords made up for use with switchboard plugs and switchboards.  The title consists of the words Cords, Switchboard, followed by a number with or without an additional word.  The number consists of three or more figures; the hundreds and thousands digits represent the number of conductors in the cord; the tens and units digits have no uniform significance.  The additional word is used only when there are differences in the cover (colour, waterproofing, etc.) of the same cord.  The length quoted in the detail is the length between the main bindings of the cord.

All standard switchboard cords are shown on Drawings Nos. 10085, 10280, 11503, 11504 and 11568.

# - Black, Blue, Green, Neutral, Red and Yellow
