For the following problems, sketch a schematic wiring diagram showing the connection of the ungrounded, grounded, and equipment grounding conductors to the wiring devices. Where switching is specified, designate the contact switching arrangement for each device (SPST, DPST, ect).

1. Two lighting outlets controlled by two switches. The tow bulbs must be in parallel, please include two SPDT switches, phase, neutral and grounding conductors.

2. A duplex receptacle with one receptacle outlet always hot and the other outlet switched from a single switch (split-wired receptacle). The receptacle has one hot all the time, must be all the time powered, while the second one have to be connected to a switch (SPST), include all phase, neutral and grounding conductors.

3. A duplex receptacle with one receptacle outlet always hot and the other outlet switched from two switch locations. The receptacle has two controlled outlets, must be powered through a switch control (SPDT), include all phase, neutral and grounding conductors.
