The maximum number of switches permitted to disconnect a service is ______?

The maximum number of switches permitted to disconnect a service is determined by safety regulations aimed at ensuring that electrical systems can be safely turned off in case of maintenance or emergencies. For most systems, especially in residential and commercial settings, having a limit on the number of disconnects helps to promote safe practices and prevents confusion during operation.

The correct answer reflects the standard set by the National Electrical Code (NEC) and local codes, which often align with these national standards. Typically, the NEC allows for a maximum of six switches or devices that can be used to disconnect power to a service. This is designed to ensure that operators are not overwhelmed with too many disconnecting means, which could lead to safety issues during an electrical emergency or maintenance period. Therefore, the maximum number of switches permitted is six, as established in line with these safety guidelines.
