What do your mean, "hot wire"?? If you are opening that PS up and digging around in it, be very careful; the capacitors hold an electrical charge long after the unit is unplugged and you can get a dangerous jolt if you touch the wrong thing.

Where can i obtain a wiring diagram

A one phase 3 wire system has a center tap. Two hots and a neutral. Typical 120/240 volts.
A three phase 4 wire system has Three hots in a Y or Delta. The Y system has three hots and the neutral comes from the center of the Y, this is the neutral and grounded conductor, 120 volts from hot to ground and 208 volts hot to hot. In a 3 phase system the voltage is not doubled hot to hot as in a single phase system because the hots are 120 degrees phased from each other and the square root of 3 is the factor, multiply the 120 volts by 1.73 to get 208 volts hot to hot. Multiply 208 by the reciprocal of 1.73 and get 120 volts. Your exact application is not given so it is not known. A delta system is a triangle and the angle of each triangle is a hot wire, one angle would be grounded or the center tap of one of the sides of the triangle. Y is the configuration of the windings of the alternator or transformer and Delta is the configuration as a triangle of the windings of the alternator or transformer where the power supply is.

With a three phase home service, you can only connect two hots from your single phase generator, and the neutral. One of the house's hot does not get connected and any three phase loads in the house should be switched off and kept from energyzing or a circuit breaker or fuse serving that 3 phase load may trip.
Only one power supply can be connected at a time. The power company power must not be connected at all while using an alternate power supply unless your power supply has means to synchronize the alternating cycle.

It is adviced that the loads be kept within 10% of their rated voltage, especially motors.

Why is my delta kitchen faucet hot cold backwards

The supplies are probably hooked up backwards. Hot to cold side and cold to hot side.

Turn a delta 400lb

I don't think this model has any on/off switch on the side of the case.
Ensure that the PSU is setup for the correct a.c. input voltage.
I assume that it is the same model as here
with a 20 pin mainboard connector.
Working from this reference
the PSU (removed from computer) may be turned on by connecting the terminal from which the green wire emerges to any of the terminals from which black wires emerges, for example pin 16 to pin 15 in the diagram (a straightened out paper clip is often used for this purpose)
Alternatively, it easier to use a psu tester
When connected in your computer find the connector which goes to the front panel on/off button. If if it's connected simply press the on button on your computer. If its not, establish from the m/b manual which are the pins to the on/off switch and connect them together for a moment. The psu should come on.

Wiring a dimmer switch with 208vac, single pole

208 Volt 2-wire is generally achieved by pulling two hot wires off 3-phase 120/208 Wye or 208 Delta, or Highleg to center tap off high leg delta.

Since each of these three phase systems also offers 120volt for lights, and a dimmer can be used for lights, then I wonder what you are using dimmer for?

208 volts.can be controlled by turning off one hot of the two hot wires.
Install dimmer on one of the hot wires, and see what happens.
Is the dimmer rated for 208 volts?

We have a Delta 172 single handle faucet. We had our hot water heater replaced. Now it takes longer for hot water to get to the faucet. Could debris (calcium build up, etc.) from the replacement get in...

Yes, debris from water heater replacements often breaks lose and gets stuck. The problem could potentially be anywhere between water heater and the faucet. The faucets shut off valves or the Delta faucet cartridge itself. Turn the hot and cold water valves off under the sink and disconnect the water supply lines from the faucet. aim the water supply lines into a bucket and turn the valves on one at a time. If there is a significant reduction in the water pressure and volume on the hot water side, you need to replace the shut off valve. If there is no reduction in water pressure, you need to clean and/or replace the Delta faucet cartridge. Contact Delta to receive free replacement parts.

What are the outputs of the varios plugs & sockets of a Delta Electronics power supply model SMP-420BB when supplied with 230 volts AC input

Forget about the individual plugs. Concentrate on the wires.

The Delta SMP - 420BB is just another
Switched Mode Power Supply.

(SMPS shortened to SMP by Delta. I'm speculating here, but I'll bet the 420 stands for 420 Watts)

No matter what the input voltage is, the SMPS will only put out three main voltages.

1) Wires with Yellow insulation are 12 Volts
2) Red wires are 5 Volts
3) Orange wires are 3.3 Volts

ANY Black wire is a Ground wire.

For example:
1) 4-pin white Molex power cable.
1 - Yellow wire
1 - Red wire
2 - Black wires

(4-pin Molex power cable is also referred to as a Peripheral power cable)

Here is more in-depth info about the various power connectors, and power cables, used in a personal computer,

Where may I find a schematic for a Delta SMP-220DB?

the green wire in the power connector shorts to ground (a black wire) in order to cut on.

You can test a power supply by doing this your self. take a paper clip and short the green wire in the connector to any back wire in the connector and if the power supply is good it will come on.

Trying to install a new stereo.

If you don't have one, buy yourself a $5.00 12volt test light, it will come in handy in situations like these, and many others. Can you not find 12volt constant in yoour old connection?
