- STW sparky club: Max current draw of a house? (roughly)
Im building a power monitoring project, and am using a SCT0013 non invasive (clamp) current monitor, but am working out whether i need to go out and buy another resistor for the burden resistor.
The clamp has a max current limit of 100A, but I cant imagine a house pulls that much, even with everything in the house turned on.
The oven (highest draw in the house) is going to be on a 30A system,the ring might be 30A?
Do you reckon 75A would cover the peak current?Posted 4 years agospooky_b329Member
My parents had a 60 amp in their 3 bed semi, and managed to blow it one afternoon.
No gas so mid afternoon the economy 7 cheap rate kicked in to top up the water (immersion heater) and 5 storage heaters, I’m one of four kids and no doubt we had all three PC’s fired up plus hifi’s etc, my mum was cooking Sunday dinner (electric hob and oven) and I expect my Dad was had his guitar and amp on.
So with gas, 75A probably good, electric heating, go for 100A. Their 60A fuse was under-rated so replaced with 100A for free…after a few hours when it got dark and my mum realised we were the only house with a power cut!Posted 4 years ago
