Question

Wireways may be installed in which location?

in areas of exposed work
in areas containing severe corrosive conditions
in areas subject to severe physical damage

Answer 1

Wireways can be installed in areas of exposed work but are not suitable for areas with severe corrosive conditions or subject to severe physical damage. They protect and conceal wires, and should be used where less robust protections would not suffice.

Step-by-step explanation:

The question pertains to the locations where wireways may be installed. Wireways are enclosed channels designed to protect and conceal cables and wires. They can be made from a variety of materials to suit different environmental conditions.

Wireways can be installed in areas of exposed work where they can be accessible for maintenance and future changes to the wiring system. However, wireways are not typically suitable for areas containing severe corrosive conditions or areas subject to severe physical damage because they might not provide adequate protection under these circumstances. Instead, for these harsh environments, more robust forms of protection like conduit or armored cable may be necessary.

Examples of wireway installations could be in industrial settings where they protect wiring against general environmental factors, or as part of the infrastructure in settings like ships' superstructures, container vehicle bodies, or tube trains (metro trains). Additionally, although not typically considered wireways, overhead power cables may also be designed to withstand environmental exposure, often with a steel core to strengthen them.

Answer 2

Wireways can be installed in areas of exposed work as enclosures for wires and cables. They are not ideal for environments with severe corrosive conditions or where they may incur severe physical damage. Different protective systems are used for other types of transport and overhead power cables.

Step-by-step explanation:

The question is addressing the installation of wireways, which are enclosures used to protect and manage wires and cables. Wireways can be installed in areas of exposed work, meaning places where electrical installations are not concealed. However, wireways are generally not suitable for installation in locations with severe corrosive conditions or in areas subject to severe physical damage. For example, they should not be placed in environments where they are likely to be exposed to heavy impact or harmful chemicals that could degrade the material of the wireway.

Other forms of transport, such as ships' superstructures and container vehicle bodies, usually have different requirements for cable management and protection systems compared to standard wireway installations. Similarly, overhead power cables often utilize specialized components like steel core cables that provide added strength for suspension purposes.
