What must auxiliary gutters maintain in terms of continuity?

1. Mechanical and electrical

2. Physical and thermal

3. Electrical and environmental

4. Mechanical and thermal

The correct answer is: Mechanical and electrical

Auxiliary gutters must maintain continuity in terms of mechanical and electrical aspects. This means that they should ensure a constant path not only for the electrical conductors housed within them but also provide structural support, allowing for secure mounting and protection of the wiring system. Maintaining mechanical continuity ensures that the integrity of the gutter structure is preserved, which is essential for safety and operational efficiency. When looking at the other options, while physical aspects might relate to the structural form, they do not specifically communicate the requirements for ensuring safe electrical operations. Thermal continuity is indeed important related to heat management in electrical applications, but it does not independently define the critical continuity needed for the conductors themselves as well as the proper mounting and support structures necessary for effective electrical installations. Therefore, the combination of mechanical and electrical continuity in auxiliary gutters is crucial for maintaining safety and functionality in electrical systems.
