Maintaining Your Switchgear | EC&M to the switchgear itself can be extremely expensive, but that pales in comparison to corollary damage and the potential hazards to people. Thus, implementing an effective switchgear testing, inspection, and maintenance program is essential. Even switchgear labeled "maintenance free" requires periodic testing and maintenance.
