Final answer:
Aluminum sheathed cable must be supported at intervals not exceeding 1.5 metres.
Step-by-step explanation:
When installing aluminum sheathed cable, it is important to provide proper support to prevent sagging or excessive stress on the cable. The recommended interval for supporting aluminum sheathed cable is typically not exceeding 1.5 meters or approximately 5 feet.
Supporting the cable at regular intervals helps maintain its structural integrity and prevents it from being exposed to excessive tension or bending. This interval ensures that the cable remains securely in place and reduces the risk of damage or failure.
It is essential to follow manufacturer guidelines and local electrical codes when determining the specific support intervals for aluminum sheathed cable, as these requirements may vary based on factors such as cable diameter, load capacity, and installation conditions.
