Choosing the correct cable type for safety and efficiency is essential when setting up electrical systems. Understanding the main reasons for electrical cable failure is also important. As electricity advances, more cables are used in different environments or conditions, but wait, have you ever thought, what if in bad conditions/situations? Then, it becomes more critical to ensure your cables run smoothly and reliably when transferring electrical energy. An armoured cable made of metal provides an extra layer of protection against damage caused by various factors.

Protected cable is installed in locations exposed to mechanical damage, such as on the outsides of walls, as an alternative to conduit. Protected cable usually has a small metal ribbon to ensure electrical continuity of the safety ground. (You must run a separate ground wire in flexible conduit too; you can’t depend on the continuity of the conduit.)
