## Questions & Answers

**Q: Will this retain the kWH used after a power cut?**
A: FYI: 'The device can never be reset.'

**Q: Is this an rcd with a power monitor incorporated into it? if so is it suitable for a uk consumer unit?**
A: This (WE-521/WE-519) is not an RCD (residual current device), it's just an energy meter. It is suitable for a UK consumer unit, I've installed one in the garage.
