In wiring, what does UL mean?
laboratories for underwritersThe most well-known Underwriters Laboratories (UL) standards are to electrical products. For example, all light bulbs, lamps, and outlets sold in the United States typically bear the UL symbol and are marked as UL Listed. Actually, they issue a far greater set of standards, all of which are concerned with consumer product safety.
What is meant by "UL approved"?
When a product has the UL Listed seal, it indicates that UL has evaluated it to meet widely accepted sustainability and safety criteria. It has also been determined that there is no reasonably foreseeable risk of electric shock or fire in a Division 2 environment.
What is the rating for wire voltage?
Cable voltage ratings differ between standards. Cables often have voltage ratings of 300V and 600V. The maximum circuit voltage applied to any conductor within the cable or raceway must be equal to the insulation rating of the equipment or other installations, per CE regulations.
What is the purpose of 1000V cable?
The primary applications for the cables include power plants, airports, petrochemical plants, high-rise buildings, hotels, hospitals, and subterranean passenger transit systems.
What is meant by 600v 1000V?
They are both for ratings of AC voltage. In a slash voltage rating, phase to ground is represented by the first number, and phase to phase by the second. Thus, the maximum phase to phase and phase to ground voltages (RMS) for the aforementioned line would be 600 and 1,000 volts, respectively.
UL 224: What is the specification?
1.1 This Standard outlines the specifications for insulating tubing, which is typically round in cross-section and is made completely of extruded compounds with thermosetting, elastomeric, or thermoplastic polymer ingredients as its defining elements (see materials and ratings).
What voltage rating is 240?
A 240-volt outlet can handle voltages between 228 and 252 volts. It consists of two 120-volt lines, Phase A and Phase B. Throughout history, 240 has been called 220 because the voltage range begins in the 1920s. The house receives power from the streetside source for both phases (A and B).
Is UL1569 and UL1007 equivalent?
Numerous UL 1007 cables also satisfy CSA type TR-64 and UL 1569 requirements. The temperature ratings of the three standards differ from one another the most. With a maximum temperature of 105°C, UL 1569 has the widest temperature range of the three. Additionally, these lead wires are frequently offered in several AWG sizes.
What makes UL1015 and UL1007 different from one another?
UL1015 has a working voltage of 600V and a maximum temperature of 105 degrees; UL1007 is resistant to a working voltage of 300V and a high temperature of 80 degrees. Different insulating layer thicknesses exist. UL1015 is more substantial than UL1007.
What distinguishes UL1015 and UL1063 from one another?
UL1015 wires are resistant to chemicals and abrasions and have a maximum temperature rating of 105 degrees Celsius. The temperature rating for UL1063 wires is 90 degrees Celsius in dry conditions and 75 degrees Celsius in wet conditions.
