Google Earth's 'look back in time' feature shows that an addition was recently built on to the back of the house. From the utility side, I would assume that the upgrade to a 400 Amp service is to allow for the installation of a second panel to feed circuits in the new addition.
If the house is...
If the customer sticks with single phase, PG&E might not be planning to change the service drop at all for a conversion from 200 Amps to 400 Amps. From the utility standpoint, they only need to have facilities in place that can handle the actual load (they don't have to match the rating of the...
If load current is higher than the calculated minimum fault current in a distribution sectionalizing study, I've typically just added the average load current to the minimum fault current to get an 'adjusted minimum fault current'.
This is more likely to be an issue when using an ohm value...
My experience with the use of minimum fault current values has been while performing sectionalizing studies of distribution feeders. The interrupting rating of a protective device is compared to the maximum (bolted) fault current that it would be subjected to. The pickup setting of the...
