10.
a) True
b) False
## CORRECT --> A unit switch(es) with a marked “off” position that is part of a fixed heater and disconnects all
ungrounded conductors shall be permitted as the disconnecting means required by this article where other means for

Flexible cords are permitted only to supply portable appliances.
13.
a) True
b) False
Toasters may have live parts exposed to contact.
14.
a) True
b) False
## CORRECT --> Appliances shall have no live parts normally exposed to contact other than those parts functioning
as open-resistance heating elements, such as the heating element of a toaster, which are necessarily exposed.
The conductor between the surge arrester and the line and the surge arrester and the grounding
connection shall not be smaller than 6 AWG copper or aluminum.
15.
a) True
b) False
## CORRECT --> Line and ground connecting conductors shall not be smaller than 6 AWG copper or aluminum.
