the requirements of 110.21(B) shall be provided indicating

the location of the generator disconnecting means.

(B) Generators Installed in Parallel. Where a generator is

installed in parallel with other generators, the provisions of

445.18(A) shall be capable of isolating the generator output

terminals from the paralleling system bus. The disconnecting

means shall not be required to be located at the generator.

Expert Analysis

Modiﬁcations are made to clarify the permitted

locations for emergency shutdown devices and

marking. Section 445.18(B) is revised from “paralleling

equipment” to “paralleling system bus” to clarify the

intent of the requirement.

Leviton Solution

Powerswitch

curve top safety disconnect

switches with Inform™ technology

provides local and remote monitoring

•

Curve top design pushes water and debris

towards the side of the device and

leaves less area for buildup

• How does Inform work?

Sensors are embedded into Leviton devices

to monitor device health. Data from

sensors can be viewed locally or

remotely via Wi-Fi or Modbus RTU

• Local monitoring — Green LEDs on the cover

provide a visual indication that the device

is operating under normal conditions,

ﬂash red if there is a failure,

or ﬂash yellow if there is a buildup of

liquid inside of the enclosure that may

lead to a potential failure
