NOTES:
1.
In compliance
with
NEC
requirements
for muttimotor
and
combination
toad
equipment
(refer
to NEC Articles
430
and 440),
the
overcurrent
protective
device
for the
unit shall
be fuse
or
HACR
breaker.
Canadian
units
may
be fuse
or circuit
breaker.
2.
Unbalanced
3-Phase
Supply
Voltage
Never
operate
a motor
where
a phase
imbalance
in supply
voltage
is greater
than
2%.
Use
the following
formula
to determine
the percentage
of voltage
imbalance.
% Voltage
Imbalance
= 100 x
max
voltage
deviation
from
average
voltage
average
voltage
Example:
Supply
voltage
is 230-3-60
AB = 224 v
BC = 231 v
AC = 226 v
Average
Voltage
=
224
+ 231
+ 226
3
681
3
227
Determine
maximum
deviation
from
average
voltage.
(AB) 227
224
= 3 v
(BC)
231
227
= 4 v
(AC)
227
226
= 1 v
Maximum
deviation
is 4 v.
Determine
percent
of voltage
imbalance.
4
% Voltage
Imbalance
= 100 x
227
= 1.76%
This amount
of phase
imbalance
is satisfactory
as it is below
the
maximum
allowable
2%.
IMPORTANT:
If the
supply
voltage
phase
imbalance
is more
than
2%, contact
your
local
electric
utility
company
immediately.
