Maharashtra SSC Electrical Technology Pre-Voc/NSQF · Work through your exam, one topic at a time.
Electrical Technology is a pre-vocational/NSQF subject offered at Class 10 level under the Maharashtra State Board of Secondary and Higher Secondary Education. It is designed for SSC students who want a school-level vocational qualification that leads either into further technical study (ITI, polytechnic diploma streams) or into entry-level work as an electrician's helper, wiring assistant, or appliance service technician. The Maharashtra SSC Electrical Technology Pre-Voc/NSQF study guide has 12 sections and about 3,289 words.
01Basic Electrical Principles and Safety
This domain tests the foundation of electrical work: current, voltage, resistance, power, series and parallel circuits, AC and DC, and the safety rules that prevent shock, fire and equipment damage. The exam expects correct units, correct formula selection and safe isolation practice.
292 words, about 1 min02Electrical Materials
This domain tests the properties and selection of conductors, insulators, magnetic materials and contact materials. The exam checks whether you can match a material to its job: copper for conductivity, aluminium for lighter overhead lines, PVC for insulation, and silver or silver alloys for low-resistance contacts.
292 words, about 1 min03Tools and Measuring Instruments
This domain tests hand tools, testers and instruments used to install, test and diagnose electrical circuits. The exam expects safe use of screwdrivers, pliers, wire strippers, insulation testers, multimeters, clamp meters and energy meters, plus correct connection of meters to a circuit.
295 words, about 1 min04Wiring Systems
This domain tests the choice and installation of wiring systems: cleat, casing-and-capping, batten, conduit, concealed conduit and surface conduit. The exam checks compliance with standard wiring practice, correct cable selection, subcircuit division, colour coding and protective-device coordination.
290 words, about 1 min05Accessories and Installation Practice
