No.
Three-wire equipment in laboratories is used for anti-interference purposes in addition to safety considerations, so two-eye plugs may not be used in place of three-eye plugs when using electrical equipment in laboratories.
Laboratory use of electrical equipment, some are designed in accordance with Class I insulation, this type of electrical appliances, must be grounded, can not use two-eyed plug instead of three-eyed plug. Some are designed in accordance with Class II insulation, itself does not require grounding, can not use the three-eyed plug. In practice to distinguish between these two situations, choose the appropriate plug to achieve the purpose of safe production.
Extended information:
The three-eye plug is a three-eye plug, which is a three-eye plug. p>Three-eye plugs and three-eye sockets are used in order to connect the shell of the electrical equipment to the thick foot of the plug or the foot with the grounding symbol, and connect to the zero wire through the socket, thus realizing the protection of zero.
Three-hole socket: three-hole socket has 10A and 16A, 16A three-hole socket can withstand up to 3500 watts of electrical power.
Three-hole socket: the upper hole for the grounding wire, left zero (N) right fire (L); three-eyed socket has a special protection of zero (ground) jack, in the use of zero protection, the extra one is grounded.
