The cut off isn't in TH/s it's in kW/H and how many kW a house can support.
The electricians in this forum could probably get into specifics for you, but that's the right question you should be asking. "How many amps and how many kW can my circuit support?" Businesses, warehouses, and datacenters obviously have higher power threshold, so you can think more in tens of TH/s, but for home it's strictly how much your circuit can handle.
we are working on getting more Kw more breakers for our location. we were aware of the circuit support we just don't know how to get it yet.
a usa home may have 200 AMP 120 volt that is 24000 watts
a usa home may have 100 AMP 120 volt that is 12000 watts
I have 150 amp 120 volt that is 18000 watts
lets say ½ for the rest of the home
so 200 amp = 12000 watts
150 amp = 9000 watts
100 amp = 6000 watts
75 percent for your safety margin of 24/7/365 run time
means
200 amp = 9000 watts for mining
150 amp = 6750 watts for mining
100 amp = 4500 watts for mining
at .7 watts maybe 12 th for a 200 amp home
at .7 watts maybe 9th
at .7 watts maybe 6th
When gpu's were king my 150amp home safely ran 6200 watts doing 23 gpus non stop for 7 months
Basically this is why thread after thread says home mining is dead. not enough watts in a home.
lets says I have 2 cent power and I burn max power which lets me run 9th
the calcs below assume 2 cent power and free gear if you use 2 cent power and the cheapest gear there is the asic miner long tube . you would need 9btc to buy 9th and you would earn a little bit of money maybe 3-4 coins. so to mine at home you need 2 cent power with asic miner long tubes in house by oct 15th you need coins to stabilize at 375 usd and diff to stay at 10 percent or less.
almost no home miner can do this.
