so a 20 amp may be good for the 4 miners above on a hot summer night.

My main farm can sag to 190 volts so I use 30 amp circuits and down clock in the summer.

if we have 8 x 3500w miners

From the consumer unit have 8 x 20amp breakers with there own dedicated cable from each?

Also, can you explain this

but if your voltage drops on a brown out to 208 208 x 16 = 3328 which may trip the 20 amp circuit with constant run

202 volts x 16 = 3232 and your 20 amp breakers will trip

if the voltage drop to 202 volts(from 230/240), how will this cause the breaker to trip? Less voltage means less amps, so it should definitely not trip

okay a 3500 watt miner wants 3500 watts it not underclocked.

so 3500/240 = ? amps

and 3500/208 = ? amps

the voltage drop from 240 to 208 does ? to amps

I know the answer to those ?

The thing you need to understand is a 3500 watt machine sucks at the power line until the line provides 3500 watts. unless you set a lower clock on the miner and demand less watts.

the miner says give me my 3500 watts.

first question mark is 14.58 amps and a 20 amp breaker should do the trick without underclock.
second question mark is 16.82 amps and a 20 amp breaker may pop if you run 24/7
third question mark is amps go up.

think of the miners demand of 3500 watts like a pool to be filled

so a 1 inch hose with 240 pounds (volts) of water pressure takes less time (amps) to fill the pool

a 1 inch hose with 208 pounds (volts) of water pressure takes more time (amps) to fill the pool

the things that vary are volts and amps not watts

or in the analogy of the pool. the water pressure and the time vary and the pool size is constant.

if you have 8 pieces of 3500 watt gear with 20 amp separate breakers you may have to underclock the gear to 3000 watts in the summer. it simply depends on the power company giving you a dead solid 220 volts or more all summer long.

oh 3500/220=? amps 😀
