2.8 AC ELECTRICAL POWER WIRING
The AERCO Benchmark 1.5 Electrical Power
Wiring Guide, GF-4060, must be consulted prior
to connecting any AC power wiring to the unit.
External AC power connections are made to the
unit inside the Power Box on the front panel of
the unit. Remove the front door of the unit to
access the Power Box mounted directly above
the Control Box. Loosen the four Power Box
cover screws and remove cover to access the
AC terminal connections inside the Power Box
(Figure 2-7).
NOTE
All electrical conduit and hardware must
be installed so that it does not interfere
with the removal of any unit covers, inhibit
service/maintenance, or prevent access
between the unit and walls or another
unit.

2.8.1 Electrical Power Requirements
The AERCO Benchmark 1.5 Boiler accepts 120
VAC, single-phase, 60 Hz @ 20 A. The Power
Box contains a terminal block as shown in
Figure 2-8. In addition, a wiring diagram showing
the required AC power connections is provided
on the front cover of the Power Box.
Each Benchmark 1.5 Boiler must be connected
to a dedicated electrical circuit. NO OTHER
DEVICES SHOULD BE ON THE SAME
ELECTRICAL CIRCUIT AS THE BENCHMARK
BOILER. A means for disconnecting AC power
from the unit (such as a service switch) must be
installed near the unit for normal operation and
maintenance. All electrical connections should
be made in accordance with the National
Electrical Code and/or with any applicable local
codes.
For electrical power wiring diagrams, see the
AERCO Benchmark 1.5 Electrical Power Wiring
Guide, (GF-4060).
