3 Provisions for Service
Designers must provide emergency shutoffs and other devices to satisfy electrical codes. It is also recommended
to provide an electrical shutoff disconnect switch of suitable load carrying characteristics on or near each Hot
Water Boiler. No electrical boxes or field components should be mounted to the surface of the unit or where they
would interfere with the removal of the side or top panels for maintenance. The disconnect switch should be
mounted near the unit as illustrated in Figure 1. Wiring conduit, EMT, or other wiring paths should not be secured
to the unit, but supported externally. Electricians should be instructed as to where the wiring conduit should be
located, such as away from the relief valve discharge, drains, etc. All electrical conduit and hardware should be
installed so that it does not interfere with the removal of any cover, inhibit service or maintenance, or prevent
access between the unit and walls or another unit.
4 Unit Wiring
A dedicated protected circuit should be provided from the power source to the unit. No other electrical devices
should be permanently wired on the same circuit. An emergency switch (electrical shutoff) must be in series with
the power to the unit. Refer to Figure 4 for the wiring connections to the terminal block contained in the unit's
Power Box.
5 Multiple Unit Wiring
Whenever multiple units are installed within the same mechanical spaces, electrical code requirements call for a
single electrical shutoff for emergency use. It is the responsibility of the electrical designer to comply with local
codes and regulations affecting an individual installation.
