2. Camlock (electrical) - Wikipedia

   en.wikipedia.org/wiki/Camlock_(electrical)

   Each camlock connector carries a single phase, pole, or conductor; multiple camlock connectors will be used to make a complete electrical supply or circuit. The most common form is the 16 series, rated at 400 amperes with 105 °C terminations. Also in common use is the 15 series (mini-cam), rated at 150 amperes.

3. Interlock (engineering) - Wikipedia

   en.wikipedia.org/wiki/Interlock_(engineering)

   Only qualified personnel, who must use a tool (such as a screwdriver), are allowed to bypass the interlock. Such interlocks are called defeatable interlocks, and are specified by Underwriters Laboratory (UL) standard UL508a, and National Electrical Code (NEC) Article 409.2. Defeatable interlocks are allowed on electrical equipment up to 600 ...

4. Trapped-key interlocking - Wikipedia

   en.wikipedia.org/wiki/Trapped-key_interlocking

   This is a trapped-key interlock on the door of an electrical switchgear cabinet. It is attached with one-way security screws to discourage casual removal, which would defeat the interlock scheme. Trapped-key interlocking utilizes locks and keys for sequential control of equipment and machinery to ensure safe operation. Trapped-key interlocks ...

   Shrouded cable glands going into a flow meter. Split cable gland KVT for routing pre-terminated cables. A cable gland (more often known in the U.S. as a cord grip, cable strain relief, cable connector or cable fitting) is a device designed to attach and secure the end of an electrical cable to the equipment.

6. Disconnector - Wikipedia

   en.wikipedia.org/wiki/Disconnector

   In electrical engineering, a disconnector, disconnect switch or isolator switch is a type of switching device with visible contacts, used to ensure that an electrical circuit is completely de-energized for service or maintenance.

7. Powerlock - Wikipedia

   en.wikipedia.org/wiki/Powerlock

   Powerlock is a range of single-pole electrical connectors used for temporary high-current, low-voltage (up to 1000 V AC) applications, [2] similar to but considered safer than camlock connectors. Originally developed by Litton Veam in the mid-1990s, VEAM Powerlock is now a brand of ITT Cannon. Compatible versions are also available from other ...
