# Nuisance Tripping

> RCD/ELCB or breaker trips around outages, mornings or backup tests — the triage flow.

    <p><strong>Escalate to Kent New Energy service only</strong> — through your registered Kent
    partner channel or the Kent service desk details on your work order. Do not contact any
    third-party or component-manufacturer support line for a Kent-branded system: tickets outside
    the Kent channel are not tracked, not covered, and can void warranty handling.</p>

**Symptom:** the site's RCD/ELCB (or a breaker) trips — at every grid outage, on dewy
mornings, during the backup test, or seemingly at random.

<Warning>
  **Never bypass, bridge or remove an RCD to "get it running".** Protection stays in the
  circuit, full stop. A trip is information — read it.
</Warning>

## Check first

1. **When exactly does it trip?** Outage-linked → neutral–earth behaviour in backup. Dewy
   mornings → PV insulation. Under one appliance → that appliance. Random → measure, don't
   guess. {/* CITE: workbook T9 RCD flow */}
2. **Which device trips** — the main RCD, a sub-circuit RCD, or an MCB? An MCB is
   overcurrent, not leakage — different flow (<a href={bnwHref}>Backup Not Working</a>).
3. **Record the site's N–E voltage** in both grid and backup states — Kent service will ask
   for it. \[KNB-VAL-04]

<Warning>
  **Pending Kent validation.** \[KNB-VAL-04]
  The neutral–earth bonding scheme in backup and the approved RCD types/ratings per Kent SKU
  are under confirmation with Kent engineering. Until published here: wire PE and backup earth
  exactly per the platform AC pages, **record N–E voltage in grid and backup states** on every
  affected site, change no protection devices ad hoc, and escalate persistent outage-linked
  tripping with those readings attached.
</Warning>

## Escalate when

* Outage-linked tripping persists on a site wired exactly per the platform AC pages — send
  the N–E readings, RCD nameplate photo and trip log. \[KNB-VAL-04]
* Leakage-class faults persist after the strings insulation-test clean and connectors are
  verified dry/sound.
* Anyone proposes running without the RCD "for now" — that is a stop-work, not a workaround.
