## What is Assistant Engineer/ Electrical ?

Assistant Engineer is an entry-level executive cadre post in the Power Sector Companies such as TRSNCO, GENCO, DISCOMs within the States of Telangana and Andhra Pradesh.

LATEST UPDATE The nomenclature for this post is changed as Assistant Executive Engineer within Andhra Pradesh Power Sector Companies since 2019.

As per APSEB Service Regulations adopted by the both states companies and as amended from time to time, the post of Assistant Engineer/Assistant Executive Engineer falls under Engineering Services (ES) Establishment and classified as Class-II Service within the board. This is equivalent to Group-2 post within state government.

As per IPC Section 21, any posts under PSUs doesn't fall under Gazzeted Category, however we see many AEs and above cadre officers using green pen and give gazzeted signatures.

The post of Assistant Engineer, abbreviated as AE is a highly sought after post by graduates in Electrical Engineering.

Within the society as well, the level of respect, reception for the post of AE is much higher. Hence, even parents aspire their children must crack this exam.

## What is the salary of an Assistant Engineer/Electrical?

The salary of a regular govt. employee has the following components:

EARNINGS:-

Basic Pay

Dearness Allowance (DA) (as a % of Basic Pay, revised every January & July)

House rend Allowance (HRA) (as a % of Basic Pay)

Other Allowances such as Medical, Conveyance, CCA (City Compensatory Allowance ) etc.

GROSS SALARY = 1 + 2+ 3 + 4

DEDUCTIONS:-

Professional Tax @ Rs. 200/-

Medical Scheme Deduction

eEPF Contribution (12.5% of Basic+DA)

Income Tax

Other recoveries, deductions like Loans, LIC policy etc

TOTAL DECUCTIONS = 5 + 6+ 7 + 8+ 9

NET SALARY = GROSS SALARY - TOTAL DEDUCTIONS

## Modes of Selection

As per service Rules in both the states, there are 2 ways to appoint candidates for this post

By Direct Recruitment

By Promotion from post of Sub Engineer (Telangana), Junior Engineer (Andhra Pradesh)

## Direct Recruitment: Selection Process

In Telangana:

Purely on the basis of Merit in written exam conducted by the company itself and Rule of Reservation . No Interview will be conducted.

In Andhra Pradesh:

LATEST UPDATE : In May-2021, APGENCO has amended their service regulations and as per new process, the section will be based on GATE score and no written exam will be conducted

However other companies like APTRANSCO, APDISCOMs haven't yet issued any order adopting the order of APGENCO. So it means they may conduct their own written test. So, Lets wait and see.
