Is ELCB substitute of body earthing of portable electrical Equipment


 
 
Very often at construction site or another, issue of protection from electrical shock  in event of leakage/fault currents from portable electrical tools/machines e.g. welding machine surfaces. Safety practitioners  struggle a lot to ensure that electrical shock related injuries do not happen while using such portable electrical machinery. But it always remains a question of debate  as which provides the best protection, ELCB or Body earthing or combination of both.
I would like here to explain the importance of Body earthing.. Good integrated earthing system is indispensable for touch shock or protection of machine from damage and fire. The selection of earth wire of suitable capacity and material is key to the protection and integrity of it is even more important. Robust earthing  gives active protection against the touch shock and saves life. Contrary to this ELCB is a passive protection against the danger and if it malfunctions or improperly fitted, it fails to save the life. Hence provision of ELCB in upstream of power supply cable may not replace the need of providing Body earthing.
 
However combination of both is a two layers protection against the electrical hazards. and is the best solution.

    This is an insightful discussion on whether an ELCB can truly replace traditional body earthing for portable electrical equipment. While ELCBs offer protection against electric shock by detecting leakage current, they shouldn’t be considered a complete substitute for proper earthing, which provides a direct low-resistance path to ground. Both systems serve different but complementary purposes in electrical safety.

    As a student exploring this topic, I found this article very helpful. I recently came across electrical engineering assignment help resources that explain how earthing systems and ELCBs work together to ensure safety in domestic and industrial circuits. Understanding these principles is essential for anyone studying power systems or safety engineering. Great post—thanks for sharing!

@safetitude: 6-Steps Total Safety Culture Model

@safetitude: 6-Steps Total Safety Culture Model Further, an extension to 2 earlier posts that intended to enhance Safety performance and to build and establish a Total Safety Culture (TSC), this is one proprietary designed model as a guide to the journey. The strategy can be started with a small model with a selection of a change agent ( a worker with right safety attitude and zealous to take forward) and making him work through various stages of the model. Once one cycle is established, this can be repeated on the bigger scale until every worker in a business unit is covered. This also can be extended to higher management members in a later phase of implementation.

Are you responsible for Safety-Know from your responses?

In blog dated 28th November 2016, 10 leading questions were given to respond in order to know the commitment of any person towards Safety. Based on one’s understanding and commitment, the total score from the responses will grossly indicate the status. May read the score and its interpretation as below: Score<25: Need improvement, need to go beyond the compliance (situation based safety) to safety Score >25: Good start; you are change agent in safety, seek for further improvement Score>30: Fairly good, keep on doing the right things with action plan to improve Score >35: Well done, sustain it however; identify the factors which are needed for one level higher Score>40: Excellent, you are asset to build the total safety culture in the organisation
