*Some simple information that Electrical Power users need to know*

Where Fuse, Circuit Breaker, Isolator etc. should be installed ? The isolator should be placed where it is needed, and care should be taken when designing.

Mainly Isolator required
1. In the incomers of all switchboards / DBs.
2. Near all electrical appliances (within 3 meters)
3. Fire pump circuit
4. To turn off and lock for the license on the solar circuit
5. Occasionally on all circuits requiring maintenance

Whereas, all circuits that require overload protection and short circuit protection must have an MCB (or other circuit breaker) or fuse. If the fuse is installed, its combinations SFU, SDU, FS, FD, FSD, etc. can be used.

When using MCB you need to look at its Curve (B, C, D, etc.), graphic symbol, Current rating (both A & kA) etc. There are a number of things like this that an average person should be aware of when buying it, not too deep (Not deep technical). MCB also comes with Isolator feature. How to identify them. Such information are contained in subsequent videos.
