What is the correct order of the following operations, performed for conducting the estimation?

a) Wiring layout

b) Calculation of the total number of connections

c) Selection of the main switch board

Correct Order of Operations for Conducting Estimation:

To conduct an accurate estimation for an electrical installation, the operations should be performed in a logical and systematic sequence. The correct order ensures that all necessary components are considered and that the estimation process is efficient and accurate. The steps are as follows:

This is the first step where the layout of the wiring is planned and drawn. It involves determining the path of the wiring and the placement of various electrical components like outlets, switches, and fixtures. This step sets the foundation for the entire estimation process.

After the wiring layout is planned, the next step is to calculate the total number of connections required. This includes counting all the necessary connections for outlets, switches, fixtures, and other components in the installation. This step ensures that all electrical connections are accounted for in the estimation.

Once the total number of connections is known, the appropriate main switch board can be selected based on the requirements of the installation, including the total load and the type of circuits involved. This step finalizes the components needed for the installation.

Conclusion:

The correct order of the operations is:

a) Wiring layout

b) Calculation of the total number of connections

c) Selection of the main switch board
