Location and condition
of the item concerned
Check results
Check whether the out-
put neutral point is con-
nected to a load (single-
phase, three-wire sys-
tem).
No
A load is connected in
a single-phase, three-
wire system (delta
connection). In delta
connection, the pres-
ence of unbalance
between three-wire
currents may disable
the generation of
rated output.

the load (single-phase, three-wire
system).
