Currently triphase:
100V 50A
200V 120A
I hoped to have 100V 100A, but the technician said 100 triphase breaker don't exist... only 50A, 75A and (like the original one 150A). So he want instead to put a twice 50A breaker ... the device he described don't make sense and don't seems to exist on this planet... It would have to be an hybrid with 2 50A phase rating and a 100A return rating in the middle
Meanwhile I came back the day after that argument with a JIS Hitachi 3P 100A (400 or 500V can't remember) breaker from the hardware store.
Sooo...
It's gonna be epic...
It's gonna be bad...
And it's supposed to take 4 hours...
/le sux...
//December bill was 75 000 yens... with main breaker blowing 5 to 7 times a week

///Huge bills with availability are sort of ok... huge bills with constant fear of tripping the breaker are unbearable...
