Kerala PSC Assistant Electrical Inspector Syllabus

Kerala PSC has invited applications from electrical engineering graduates below 36 years towards the Assistant Electrical Inspector in November 2020. This post is considered as one of the highly desired technical posts in Kerala State services. Selected candidates will be posted in Gazetted rank level in the pay scale of Rs. 39500-Rs. 83000. The last recruitment was in 2016, and 93 candidates got the advice memo from that rank list. Here we are discussing the Kerala PSC Assistant Electrical inspector syllabus in detail. The exam will have 100 questions fo 01 hours 15 minutes, and fortunately, all these questions will be from technical topics only.

Kerala PSC Assistant Electrical Inspector Syllabus

The latest syllabus for the Assistant Electrical Inspector is yet to published by the Kerala PSC. According to the latest updates, PSC has subsequently removed the General Awareness, Numerical Ability & Reasoning, and Language section from all technical papers. So the Assistant Electrical Inspector question paper would have only technical questions making it easier for the engineering graduates. Let’s check the Kerala PSC Assistant Electrical Inspector Syllabus (tentative) in detail.

The previous year pattern for the Assistant Electrical Inspector recruitment exam is:

Among them, 40 questions were numerical and the remaining 60 were theoretical questions.

• Previous Year Cut-off Score: 51.33
