1910 – "The Black & Decker Manufacturing Company" was founded by S. Duncan Black (1883–1951) and Alonzo G. Decker (1884–1956) as a small machine shop in Baltimore in September. Decker, who had only a seventh grade education, had met Black in 1906, when they were both 23-year-old workers at the Rowland Telegraph Company.
Black & Decker had trouble keeping up with demand for the Workmate in the UK, but was still unconvinced of how well the Workmate would be accepted in the United States. As a test of demand, the UK-manufactured Workmate WM325 was introduced to the United States market in 1974 as the Model 79-001 Type E ("E" for England).
In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to ...
Renewable fuses (rewirable or cartridge) allow user replacement, but this can be hazardous as it is easy to put a higher-rated or double fuse element (link or wire) into the holder (overfusing), or simply fitting it with copper wire or even a totally different type of conducting object (coins, hairpins, paper clips, nails, etc.) to the existing ...
Modern home buyers often find that existing K&T systems lack the capacity for today's levels of power use. First-generation wiring systems became susceptible to abuse by homeowners who would replace blown fuses with fuses rated for higher current. This overfusing of the circuits subjects wiring to higher levels of current and risks heat damage ...
Automotive fuses are typically housed inside one or more fuse boxes (also called an integrated power module (IPM)) within the vehicle, typically on one side of the engine compartment and/or under the dash near the steering wheel. Some fuses or circuit breakers may nonetheless be placed elsewhere, such as near the cabin fan or air bag controller.
However "this fuse soon replaced the less reliable fuses which were made of straws or quills filled with black powder, thus greatly reducing the hazard of accidental explosions in mining or construction." [8] Word of the reliability of Bickford's safety fuse spread, and was soon in large demand across world markets. [9]
[53] The original BS 1363:1947 specified fuse ratings of 3 A, 7 A and 13 A. [54] The current version of the fuse standard, BS 1362:1973, allows any fuse rating up to 13 A, with 3 A (coloured red) and 13 A (coloured brown) as the preferred (but not mandated) values when used in a plug. All other ratings are to be coloured black.
