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 ...
On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts. For example, on a wye to delta conversion, when cutouts are used on the wye side and only 1 out of 3 of the cutout fuses open, some customers on the delta side have a low voltage condition, due to voltage transfer through the transformer windings. Low voltage ...
For pole-mounted transformers, this is usually a 'fused cutout.' An electrical fault melts the fuse, and the device drops open to give a visual indication of trouble. Lineworkers can also manually open it while the line is energized using insulated hot sticks. In some cases, completely self-protected transformers are used, which have a circuit ...
In electrical engineering, IEC 60269 is a set of technical standards for low-voltage power fuses. [1] The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices.
An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire typically four American wire gauge (AWG) sizes smaller than the wire that is being protected. For example, an AWG 16 fusible link might be used to protect AWG 12 wiring.
Retail reading. The final monthly retail sales report before the start of the holiday shopping season is set for release on Thursday. Economists estimate retail sales increased 0.3% over the prior ...
reeling from the death of a young man who by all accounts had a bright future ahead of him. As the case began to unfold a few weeks ago, the ACLU highlighted the need for an unbiased, professional, thorough outside investigation into the shooting and called on federal and state officials to initiate this type of examination of the case.
This is the patented Schultz dropout fuse cutout. All of the defendants in this case are manufacturers of electrical devices, the most important of which for purposes of this case are dropout fuse cutouts, which are devices for breaking electrical power circuits. The defendants engaged in a conspiracy to fix the prices of these devices.
