These electrical supplies shall be permitted to include
additional receptacles that have congurations in accordance
with 551.81. The weather-resistant requirement for
50-ampere, 125/250-volt receptacles shall become effective
January 1, 2026.
Informational Note: The percentage of 50-ampere sites required by
551.71 could be inadequate for seasonal recreational vehicle sites
serving a higher percentage of recreational vehicles with 50-ampere
electrical systems. In that type of recreational vehicle park, the
percentage of 50-ampere sites could approach 100 percent.

Site Equipment.
Ground-fault circuit-interrupter protection shall only
be required for 125-volt, single-phase, 15 and
20-ampere receptacles
Expert Analysis
A revision has been accepted that covers requirements
for 30 and 50-ampere receptacles that requires them to
be weather-resistant and conform to Figure 551.46(C)(1)
in the NEC. The weather-resistant requirement for
the 50-ampere receptacles become eective
January 1, 2026.
Leviton Note: Looking carefully at the language used in this article it
says “shall each be equipped with a XX-amp, YYY volt weather-resistant
receptacle” and additional receptacles are permitted as long as they
conform to 551.81. However the article doesn’t say that these additional
receptacles must be WR, nor does 551.81.
In addition, the WR requirement for 50 Amp takes eect Jan. 1, 2026,
however no grace period was given for the 30 Amp receptacle.
