FAQ

• What does "interlocked" mean on this socket?
  An interlocked socket has a mechanical or electrical lock that only allows the plug to be inserted or removed when the socket's isolating switch is in the OFF position — preventing anyone from plugging or unplugging equipment while it's live. This is typically required by site safety rules for higher-current industrial connections.
• What does 2P+E mean?
  It's a 3-pin configuration: line, neutral, and earth — the standard arrangement for single-phase 230V industrial power connections.
• What does the IP44 rating mean, and is this suitable outdoors?
  IP44 means it's protected against solid objects larger than 1mm and splashing water from any direction — suitable for outdoor use and damp site conditions, but not for full immersion or direct jetting/hosing down. Check the enclosure is fitted correctly (cover closed, gland sealed) to maintain the rating in practice.
• Can I wire this myself?
  Wiring a plug onto a flexible cable is a common competent-person task, similar to fitting a household plug, but at 16A/230V voltage the terminations must be secure and correctly torqued — if you're not confident working with industrial power connectors, have a licensed electrician do it.
• Is this compatible with standard Gewiss/IEC 60309 sockets?
  Yes — Gewiss HP-series plugs follow the IEC 60309 pin-and-sleeve standard (matched by rating, pole configuration, and colour/hour-position coding), so it mates with any compliant IEC 60309 socket of the same rating and configuration, not just other Gewiss products.
