stubuzz Posted August 9, 2023 Share Posted August 9, 2023 I have removed the AC Power connection from the main incoming cable and ran a new dedicated 2.5mm circuit from the consumer unit. The only free breaker was a 10 amp and so far it hasn't tripped. Should i change it to a 20 amp? Link to comment Share on other sites More sharing options...
Crossy Posted August 9, 2023 Share Posted August 9, 2023 What does the cable feed? If the load is less than about 8A then leave the breaker as it is, no harm. Link to comment Share on other sites More sharing options...

The other socket is in the car port and is rarely used. The AC is a Mitsubishi inverter rated at 6.8 amps. I guess the 10 amp breaker is adequate. Thanks.

A breaker is there to protect the cable, for that job you can use the rated size or anything less, if the small breaker does not trip there is no need to change it. FWIW the AC rated at 6.8 amps is unlikely to use more than 4 amps for most of the time. Also the breaker is likely to not trip until you are using over 12 amps for a reasonable period ½ hour and over 1 1 Link to comment Share on other sites More sharing options...
