Problem recently posted for my class:
Heating element rated 240v 4800W (20A) has been connected to 120/208v grounded "Y" system between two phases (208v). - Everybody egrees now 3600W / 17.3A.
1. Midpoint of the element is shorted to ground assuming 0 (zero) resistance of ground fault. What total power is rreleased during ground fault?
2. What current flow to ground?
What is your opinion on asked numbers? - Is it too hard for master electrician?
