The panel listing, breaker family, bus condition, service capacity, fault rating, conductor ampacity, grounding arrangement and local code all have to agree before a new circuit can be energized. For a real project, provide the one-line diagram, system ratings, load or protection data, environment and required tests so the equipment and work method can be verified before implementation.<\/p>","protected":false},"excerpt":{"rendered":"<p>Das Hinzuf\u00fcgen eines Schutzschalters zu einer Schalttafel ist eine technische Modifikation und keine blo\u00dfe Angelegenheit eines freien Steckplatzes.
