Expert Analysis 
A revision has been made to clarify that the required 
receptacle outlets from 210.52(G)(1) must be served 
from at least one 120-volt, 20-ampere branch circuit, 
and that this 20-ampere branch circuit is also permitted 
to serve other receptacle outlets within the garage. 
Other kinds of outlets within the garage or in other 
space(s) not included by Exception 1 are prohibited from 
being connected to the required 120-volt, 20-ampere 
branch circuit. Additional text provides clarification 
that receptacle outlets, other than those required by 
210.52(G)(1), can be served by additional 120-volt 
branch circuit(s) rated either 15- or 20-amperes.
A new Exception Number 2 was added to permit a single 
bay garage to have all outlets within that garage to be 
served by the required 120-volt, 20-ampere branch 
circuit in accordance with 210.23(A)(1) or (A)(2). The 
existing numbering of the exceptions is modified to 
account for these changes.
