Back in the 1940's, many fires were attributed to electrical sources, particularly to the use of armored cable. Apparently, the conductor insulation in the armored cable was being cut by the very sharp edges of the cut armor when terminations were being made. Two investigators found that the insertion of a hard, waxed fiber bushing between the armor and the insulated conductors would prevent damage to the insulation and the anti-short bushing was born.
The reality is, anti-short bushings were and still are a critical part of electrical safety. Do you agree? For a quick history of the the Anti-Short Bushing, click here www.anti-shortbushing.com
