Functional, basic and reinforced describe different intended insulation roles; a pairwise hipot entry does not by itself classify the entire supply or certify the finished machine.

<strong>Basic insulation<\/strong> denotes the first level of shock protection. A <strong>reinforced<\/strong> claim concerns one insulation system intended to provide the protection associated with double insulation under the applicable standard\u2019s conditions. Texas Instruments\u2019 isolation terminology explains these distinctions; it does not classify the WEHO unit pictured here.<\/p>\n<p>Supplementary insulation is a further, independent layer associated with basic insulation. Keep it distinct from the three headline categories rather than using \u201creinforced\u201d as a loose adjective for any design that seems robust. The required classification for actual equipment must come from its applicable safety assessment and verified component evidence.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Read_every_barrier_pair_in_the_table\"><\/span>Read every barrier pair in the table<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The approved WEHO S-60 sheet names input-to-output, input-to-frame-ground and output-to-frame-ground test pairs.
