You need to call the DCA and get clarification.
Why is that? I was at the inspectors class on this. Read what the DCA has published about it. It says NOTHING about "Footprint"
N.J.A.C. 5:23-2.7(c)3i already allows for the
replacement of any receptacle, including those with
ground-fault circuit-interrupter protection (Section
210.8 of the 2008 NEC).
Example: A standard receptacle is to be
replaced in a bedroom. This replacement
receptacle would be required to be a tamperresistant
type and would not require a permit.
N.J.A.C. 5:23-6.8(d)3 already exempts the
requirements for branch circuits (Section 210.11 of
the 2008 NEC). We intend to exempt arc-fault
circuit-interrupter protection (Section 210.12 of the
2008 NEC) at this section of the Rehabilitation
Subcode.
Example: A conductor is to be replaced with a
new one that contains loads that do not exceed
the original branch circuit. The existing branch
circuit does not need to be replaced with one
that has arc-fault circuit-interrupter protection.
However, if a new branch circuit is installed and
serves a bedroom, then arc-fault circuitinterrupter
protection is required.
