⚡ One 100A supply. Two properties. And a sauna… 🔥
I inherited this second-fix job with a bit of a challenge.
There was a single 100A incoming supply feeding two properties, and pretty much everything was electric.
Both properties had heat pumps, electric ovens, hobs, microwaves, dishwashers, washing machines and Megaflo cylinders. There was also an EV charger — and then they decided they wanted a sauna! 😂
The challenge was figuring out how to make the sauna work without everything coming on at once and blowing the incoming main fuse.
So I had to come up with a solution to manage the available supply and make sure the sauna could operate without exceeding what the incoming supply could provide.
Have a look at the video to see what I came up with.
I’d be interested to hear how other electricians would have approached this. If you’ve got a different solution or think there’s a better way of doing it, let me know in the comments. Always interested to hear how other sparks tackle these situations. ⚡
