Quick electrical question.
I have a 220v outlet with a 30 amp breaker. Can I plug a 220-110 step down transformer to the the 220v outlet and run more than 30 amps on 110v?
There's site transformers like this that are 10kVa and output 2x32amp or 4x16amp
Nope. The breaker will trigger at 30A, no matter the voltage is. Sure, it will be beside the orignial characteristic, so you might get a few more amps. The voltage shown at the breaker ist only for arc interruption. alos, google is your friend: https://en.wikipedia.org/wiki/Circuit_breaker
you're confused. the rule of thumb for a x-former is 'power in = power out', so 60A on the secondary only requires 30A on the primary to make the equation true. the breaker will not blow with 30A on the secondary, coz it's just passing the 15A the primary needs.
Here we can get 6000 watt output 220-110 stepdown transformers off the shelf in your average hardware or electrical store.
While they are expensive they are fairly compact in size 10"x8"x6".
you're right, i see. i only looked at the 30A breaker, thst surely will trigger in the current exceeds the 30A. But with the (step down) transformator OP will get 60A@110V - or 120A@55V and so on. my fault.
Before I understood it I always wondered why a 150KW generator needed a 75-95 mm cable (depending on distance) and the power company could send power to 10's of thousands of people through 75mm cable. If it is even that fat.
