Grill Stand : It is made of chromium/nickel plated MS rods and hinged to the body. It supports
the vessels kept on the heater and acts as a barrier between the exposed heater element and
the vessel, as shown in Fig. 8.4. For safety, this grill should have electrically continuity to the
body, and both must have earth connection. A properly earthed grill and body will enable the
fuse to blow in case of accidental contact of live parts with them, thereby avoiding shock to the
user.
Heater Socket : This is used for plugging the power supply appliance plug. The socket, shown
in Fig. 8.4 has two male terminals, one for the phase and the other for the neutral. However, for
safety, the heater body should be connected to the general mass of earth through the earth
continuity conductor. For this, the appliance plug, shown in Fig. 8.5, has two spring loaded,
metallic clips on either side of it which makes the contact with metallic enclosure of the socket
when plugged. As rusting prevents proper contact of these clips with the socket, for safety,
these clips and sockets are made of nickel plated brass.
