Hi all, I'm new here and would be thankful for some advice... I'm thinking about installing a heat pump. Our house main fuse is a 64A one, and I'm told the pump would at max take 24 A. So I'm thinking about upgrading our main fuse. I'm thinking of asking for 100A to give ourselves some headroom, but 80A might also do. Power network asks about the meter tails... Would you guys be able to see from the photo if these tails are 16 or 25mm2? (I'm told they need to be 25 for 100A). The fuse board has a main circuit breaker of 100A so the rest of the setup looks OK? Are there any downside to getting a larger main fuse than what is strictly needed? Thank you very much in advance for your help!
