    Subpanel feeder breaker size?

    This is a solar tie in generating 22 amps max current, hence the 25a/2p breaker on the subpanel but is there any reason the breaker feeding the subpanel has to be an 80a/2p? Can it be a 50a/2p? Attachments IMG_0010.jpeg 514.6 KB · Views: 2

    amp/ wire size noob ?

    when wiring a 240v 50 amp breaker, for example, does each hot wire have to be rated for 50 amps or 25 amps per wire? 100 amp breaker, 50 amps per wire or 100 per wire. I think I know the answer but not sure. thx.

    Does SPD MCB size matter?

    Does this matter? I've fitted a Fusebox consumer unit and I didn't have enough 32A MCB's but too many 6A's. The SPD is fed from a 32A one, what's the deal with swapping them around. They are voltage operated not current operated so should be fine right?
