need help,
please can someone tell me how can i calculate the main
breaker and branches breakers to distribution panels (MDB)
depending on the load ampere .. i really need it but can't
find any site >>

Answer / nandhu
from the load u just calculate
the load current ,multiply by
1.5 ,diversity factor and find
the next higher value in the
breakers chart and u choose ,its
very simple

When MICC cables used ?
In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.
when we increase load , current drawn from source also increases why ?
