2) Is ungrounded.
N/A
20.7
With reference to 20.6, the conductor to be grounded shall be
one of the output circuit conductors.
N/A
20.8
With reference to 20.6, when the primary circuit to the
transformer is derived from the secondary of another
transformer, that circuit shall either be:
N/A
a) Grounded in accordance with 20.9 and 20.10;
N/A
b) Evaluated as being ungrounded; or
N/A
c) Ungrounded.
N/A
20.9
Grounding of the circuits specified in 20.2 - 20.8 shall be made
by a bonding jumper connected between the conductor to be
grounded and dead metal parts that are grounded via the
equipment grounding conductor.
N/A
Exception: The following provisions may be made so that the
circuit is able to be grounded in the field:
N/A
a) A field-wiring terminal intended for use with a conductor
size specified in Column4 of Table 17.2 and identified in
accordance with 12.2.12 or 12.2.13 shall be connected to the
circuit by a bonding jumper of a size not less than specified in
Column 4 of Table 17.2; and
N/A
b) A marking identifying the circuit as a separately derived
source and referencing the instruction manual in accordance
with 61.2.13.
N/A
20.10
The size of the bonding jumper specified in 20.9 shall be,
based on the current rating of the circuit, not less than the value
specified in Column 4 of Table 17.2.
Not fixed units and of units
having standard
configuration grounding
type receptacles for the
output ac power
connections.
N/A
20.11
A fixed unit shall be provided with a terminal that complies
with 12.2.3 - 12.2.9 for connection of the grounding electrode
conductor to the metal enclosure or equipment grounding
conductor described in 20.9 (a) and (b). The terminal shall be:
N/A
a) Capable of securing a conductor size, based on the
maximum current rating of the circuit, as specified in Column 3
of Table 17.2; and
N/A
b) Marked as described in 61.2.14.
N/A
20.12
For a unit having a polarized receptacle, lead, or terminal
identified as a grounded circuit (see 12.2.12 and 12.2.13) that
is not grounded at the unit itself because of an electrical
connection to supply conductors originating in another wiring
system [see 19.2(c)(1), 19.4(c), and 19.6(c)], a risk of electric
shock shall not exist between ground and the grounded circuit
contact, terminal, or lead. Compliance with this requirement
shall be determined by the test specified in 53.1.
N/A
Exception: The test described in 53.1 is not required when the
input neutral and output neutral conductors are solidly
connected together, that is, no electronic components
connected between the neutral conductors.

21.1
A current-carrying part shall be of silver, copper, a copper alloy,
or other material acceptable for the application.
