What should I do when a Hexing meter shows C.510 failed and power is out?
Answer
Treat this as a utility meter and supply issue, not a phone or app glitch. Check for a wider outage, note the exact Hexing code such as C.510 failed, confirm whether neighbors still have power, and contact your electricity supplier with the meter number. Do not open sealed meter compartments or bypass the meter.
Before you start: stop right away if…
- Do not open sealed meter compartments, cut seals, or bypass a utility meter; that can be dangerous and unlawful.
- Unexpected callers or visitors demanding cash to restore power are a common scam pattern.
Follow these steps
Confirm the outage scope
Check whether lights and outlets are out only in part of the home, the whole home, or also at neighboring properties. Look outside for utility work or a wider street outage if it is safe to do so.
You should see: You know whether this is likely a single-home meter issue or a wider supply outage.
Record the Hexing meter details
Write down the full message on the Hexing meter, including C.510 failed or any other codes, plus the meter number and whether credit still shows.
You should see: You have the exact code and meter identity ready for the utility.
Check only customer-accessible breakers
If you have a customer main breaker or distribution board that is meant to be user-operated, check for a tripped breaker and reset it once if your local guidance allows. Do not force sealed utility covers.
You should see: Power returns after a safe breaker reset, or breakers stay on while the outage continues.
Contact the electricity supplier
Call or use the official app/website for your electricity supplier. Report that electricity went out, the Hexing meter shows C.510 failed or failed status, and that credit may still be present with no supply.
You should see: The supplier logs the fault, explains whether a token reload, remote reset, or technician visit is needed.
Stop and wait for authorized help if seals are involved
If the meter remains unresponsive or the box is sealed, wait for the utility or a licensed electrician. Do not attempt wiring bypasses or unofficial unlock devices.
You should see: Restoration is handled through authorized utility or electrical channels only.

Extra tips
What to look for: The exact meter message, such as Hexing meter shows C.510 failed, whether credit still displays, and whether the main breaker or neighbors still have power.
Before you change anything: Stay clear of exposed wiring and do not remove utility seals. Write down the meter number and full error text. Check whether nearby homes or the street are also without power. Never pay an unexpected person who arrives unasked claiming they can unlock the meter for cash.
