3 1k's are only 15amps you could run that on the 30amp breaker with no problem for sure but 6 1k's are 30amps and the breaker is only 30amps so how do you run that cause the available is only 24 out of a 30 ( i remember my electrician friend told me that too, my wiring setup with the 10-3 wire it could handle 6 1k's but i ask him the breaker is only 30amp and with all 6 1k's it would be 30amp so how can it be? )
