Ward Brooke and Co. Ltd. has recently extended its range of heavy-duty terminal blocks by the addition of polarized models, particularly suitable for use in conjunction with unskilled labour. They are suitable for application in fields such as ship building, welding, traction, nuclear engineering, transformer manufacture, locomotive engineering, etc., and provide a foolproof method of connection by virtue of the fact that each stud is of a different size (6 U. N.C., 10 U. N. F., U. N. F. is a typical example(.
The new blocks, which offer up to three ways on one unit with up-to four connections per stud, have inherent anti-rotational shorting characteristics in the form of larger than normal spacing between the stud mountings. For practical purposes the blocks are virtually unbreakable (also of importance when considering unskilled labour) constructional materials being nylon for normal temperature operations in the range —65 to 110 deg C or silicone resin for temperatures of —65 to 350 deg C. Other important features include the height of the barriers between the studs which results in an exceptionally long creep path and the use of inter-terminal links wh ich ensures an effective reduction in wiring labour costs. As with all the company's terminal blocks, a complete range of accessories is available including nuts, washers, mounting pillars, covers and spacers.
