Hello,

Does anyone know if there are any websites that have circuit diagrams
for a mains warning alarm that sounds when the mains is off?

We occasionally find that the circuit breaker trips for a circuit in
the kitchen and if left unnoticed, the food in the freezer could thaw
out.

Thanks.

If you want to do it yourself, it would just need a mains voltage relay, and
a battery powered alarm sounder ...
