According to Ken Lovorn-- *

Factory-mounted vibration isolators on gensets are not adequate for sensitive installations:

According to Ken Lovorn-- *

Inertia pads should be large enough for enclosures to fit over generator and against the pad:

According to Ken Lovorn-- *

Having a properly sized generator fail to assume load is a sign of an improperly sequenced ATS:

According to Ken Lovorn-- *

ATS sequencing issues include:

According to Ken Lovorn-- *

Load characteristics do not include with one of the following:

According to Keith Lane-- *

Often times a more critical parameter in sizing a generator is the maximum starting kVA and maximum starting kW allowed:

According to Keith Lane-- *

A larger generator with reduced impedance can reduce the effects caused by the non-linear load, which will compensate for voltage distortion from non-linear loads.

According to Keith Lane-- *

When the generator is considered a separately derived source, the neutral and ground are tied together at the generator; a 4-pole transfer switch is optional:

According to Keith Lane-- *

When the generator is not considered a separately derived source, the neutral and ground are not tied together at the generator and  a 3- pole transfer switch must be utilized:

According to Keith Lane-- *

A modified differential grounding system is required when you have multi-source systems with 3-pole transformer switches:
