Technical training
Solar Technical Training Standard / V1 02072025
38) The participants can recognise that not all circuits on a solar array are protected by GFCI/RCD’s (Knowledge, basic level)
39) The participants can recognise the relationship between current and contact time (Knowledge, basic level)
40) The participants can recognise the consequences of receiving a shock on a circuit protected by a GFCI and on a circuit without GFCI (Knowledge, basic level)
The instructor shall:
Explain the function and importance of GFCI/RCD and protective earth in tools and equipment.
Explain what can happen when a tool is used without protective earth and GFCI/RCD, and the consequence of improper grounding on tools or equipment in e.g. different situations:
a.
situation, where there is no PE and, no GFCI/RCD
b.
situation, where there is PE but, no GFCI/RCD
c.
situation, where there is both PE and GFCI/RCD
Explain how to identify double isolated tools and that they do not require grounding.
Explain the importance of grounding an external generator in accordance with the manufacturer’s manual, local legislation and company rules.
Show examples of and explain the symbol of GFCI/RCD and PE.
Explain that not all circuits on a solar panel system are protected by GFCI/RCD’s.
Compare the consequences of receiving a shock on a circuit protected by a GFCI and on a circuit without GFCI.
Test the participants’ understanding of PE and GFCI/RCD (e.g. with a questionnaire or multiple- choice questions about PE and GFCI/RCD)
Give constructive feedback on the results of the participants’ answers, explain the reasons why the answers were correct or incorrect, and e.g. show the realistic consequences of a correct or incorrect answer to provide the participants with a sense of the real-world consequences
The participants shall:
Provide answers to the test about PE and GFCI/RCD
