110.21(A)(2), 240.2, 404.16(A)(B)(C)(D)
and 406.2 Reconditioned Equipment
Change Summary
• The NEC has changed and added to the list of what
types of electrical equipment can and can’t be
reconditioned throughout the Code. The equipment
identified here are the most commonly used in
everyday installations. Do to space constraints in
this guide, we did not list all of the less common
equipment but if reconditioning is your thing,
you may want to look to 410.2 (Lamps),
411.2 (Low Volt Lighting), 430.2 (Motors),
700.2 (Transfer Switches).
110.21 Marking
(A) Equipment Markings.
(2) Reconditioned Equipment. Reconditioned equipment
shall be marked with the following:
(1) Name, trademark, or other descriptive marking of the
organization that performed the reconditioning
(2) The date of the reconditioning
(3) the term reconditioned or other approved wording or
symbol indicating that the equipment has been reconditioned.
The original listing mark shall be removed or made
permanently illegible. The equipment nameplate shall not
be required to be removed or made permanently illegible,
only the part of the nameplate that includes the listing mark
if applicable. Approval of the reconditioned equipment shall
not be based solely on the equipment’s original listing.
240.2 Reconditioned Equipment.
(A) Reconditioning Not Permitted. The following
equipment shall not be reconditioned:
(1) Equipment providing ground-fault protection of
equipment
(2) Ground-fault circuit interrupters
(3) Low-voltage fuseholders and low-voltage renewable
fuses
(4) Molded-case circuit breakers
(B) Reconditioning Permitted. The following equipment
shall be permitted to be reconditioned:

Reconditioned equipment shall be listed as reconditioned
