Requirements for Single-Pole Switch Configuration in Distribution Boxes
These requirements are detailed in AS/NZS 3439 or AS/NZS 61439 series. 3 ) • Reduced clearances and creepage distances are allowed for equipment meeting specific standards. Identify the Input and Output sides of the MCBs and RCCBs. A single pole switch is designed to control a single circuit, allowing users to turn a light or device on or off from one location. The fault current clearing time setting is required to be achieved from inverse definite minimum time (IDMT) relay or over current relay (OCR) of the vacuum circuit breaker (VCB) panel. Where only load breaking switch (LBS) is available and no VCB panel is available fault current clearing time. The most basic form of lighting control is the SPST (single-pole, single-throw) switch.
