All equipment in a PV system - conductors and all components - have a maximum amount of current that they can handle and should therefore be protected from currents that could exceed their maximum rated current. Otherwise, an electrical fire can result. Devices that protect equipment from excess current are called [[Overcurrent protection|overcurrent protection devices (OCPDs)]], the most common of which are breakers and fuses. Additionally, in any system it is necessary to isolate all components of a PV system from all potential power sources in order to be able to work safely for maintenance or troubleshooting. Both of these functions can be often be performed by an [[Overcurrent protection|overcurrent protection device]], but a seperate [[Disconnects|means of disconnection]] may be necessary for various components. For all articles on OCPDs and disconnects see [[:Category:Overcurrent protection and disconnects|overcurrent protection and disconnects]].
