2. \u010co je ochrana proti v\u00fdbuchu?<\/strong><\/h2>

Do zabr\u00e1ni\u0165 v\u00fdbuchom<\/strong>, mus\u00ed by\u0165 kontrolovan\u00fd aspo\u0148 jeden z troch k\u013e\u00fa\u010dov\u00fdch faktorov:<\/p>

    Elektrick\u00e9 zariadenie je potenci\u00e1lny zdroj zap\u00e1lenia<\/strong> z d\u00f4vodu:

    Elektrick\u00e9 zariadenia odoln\u00e9 vo\u010di v\u00fdbuchu sa delia do dvoch kateg\u00f3ri\u00ed:<\/p>
