The key can then be used to unlock the kiln door. While the key is removed from the switch interlock, a plunger from the interlock mechanically prevents the power switch from being turned on. Power cannot be re-applied to the kiln until the kiln door is locked, releasing the key, and the key is then returned to the power switch interlock. [5]
Power cannot be re-applied to the kiln until the kiln door is locked, releasing the key, and the key is then returned to the disconnecting switch interlock. [1] A similar two-part interlock system can be used anywhere it is necessary to ensure the energy supply to a machine is interrupted before the machine is entered for adjustment or maintenance.
Without a UL Listing, some electrical inspectors will not allow the use of these interlock kits. With kits installed on the electrical panel's cover, removing the cover could allow the generator backfeed breaker to be turned on while the main is on, [4] potentially energizing power lines or overloading the generator, if the generator is connected.
The interlock device is located inside the vehicle, near the driver’s seat, and is directly connected to the engine’s ignition system. [1] It is a form of electronic monitoring . An ignition interlock interrupts the signal from the ignition to the starter until a valid breath sample is provided that meets maximal alcohol guidelines in that ...
IEC 60364 Electrical Installations for Buildings is the International Electrotechnical Commission (IEC)'s international standard on electrical installations of buildings.This standard is an attempt to harmonize national wiring standards in an IEC standard and is published in the European Union by CENELEC as "HD 60364".
"Switched socket-outlets and connectors with or without interlock" applies to self-contained products that combine within a single enclosure, a socket-outlet or connector according to IEC 60309-1 or IEC 60309-2 and a switching device, with a rated operating voltage not exceeding 1000 VDC or VAC and 500 Hz, and a rated current not exceeding 800 A.
Railway interlocking is of British origin, where numerous patents were granted. In June 1856, John Saxby received the first patent for interlocking switches and signals. [2] [3]: 23–24 In 1868, Saxby (of Saxby & Farmer) [4] was awarded a patent for what is known today in North America as “preliminary latch locking”.
Electric locks use magnets, solenoids, or motors to actuate the lock by either supplying or removing power.Operating the lock can be as simple as using a switch, for example an apartment intercom door release, or as complex as a biometric based access control system.
