Is it within code to hard wire a fluorescant light fixture into a 20 amp branch circuit that is now designated for general use utility receptacles?

It is not good practice in new wiring, but done all the time as part of a retrofit. Use 12 AWG wiring and make sure the circuit is not overloaded.

How do you wire a 240 volt street light circuit?
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
Can a single pole switch replace a starter in fluorescent lamps?
No, a switch is used to control the circuit voltage that is applied to the fixture for turning the fixture on and off. The starter in the fluorescent fixture is used to start the current flowing through the filaments in the fixture's tubes. After a specific time, the starter heats up the circuit is opened and the current then flows through the fluorescent tubes.
Can a single pole switch replace a starter in a tube light?
No. Starter comes in the circuit initially and then cuts off once the tube is on. If you use the switch, it wont be cut off automatically. If you want to use the switch manually then it technically possible to do so
Does code require a new bath vent fan to be on a dedicated circuit?
No, the bath vent fan does not need a designated circuit. If this is a new installation install a three wire cable to the fixture from a two gang switch box. Cover plates for two gang boxes can be bought with a blank on one side and a switch on the other. At some time in the future a lighted fan enclosure may be installed. This will allow the light and fans to be operated independently.
Is there a way to install a 277V light on a 120V circuit?
no ----------------------------------------------------------------------------------- Stepdown transformer. More expensive than buying the correct light fixture. Y-THINK-Y
What is the formula to figure out how many plugs and lights you can put on a circuit?
This depends upon the circuit breaker capacity. You may never load a circuit to greater than 80% of it's capacity. So you may load up to 12 Amps on a 15 Amp circuit, and, 16 Amps on a 20 Amp circuit. The National Electrical Code requires you to calculate each receptacle at 180 VA. If the circuit is 120 volts and 15 amps, you would have 1800 VA, divide by 180 VA per receptacle, equals 10 receptacles per circuit (minus the wattage of each luminaire or light fixture added to the circuit, before dividing by the 180 VA). If the circuit is 120 volts and 20 amps, you would have 2400 VA, divide by 180 VA per receptacle, equals 13.333 receptacles per circuit (round down to 13 receptacles),(minus the wattage of each luminaire or light fixture added to the circuit, before dividing by the 180 VA).

New shop 20 amp circuit 32 amp fixture how many fixtures can be put on circuit?
A 32 amp fixture can not be fed from a 20 amp breaker as the breaker will trip every time.

How do you add a fixture to an electrical circuit?
Any devices that are added to a circuit and need the full line voltage to operate, are added in parallel to any other load devices or fixtures in the circuit.
Can a single pole switch replace a starter in a tube light?
No. Starter comes in the circuit initially and then cuts off once the tube is on. If you use the switch, it wont be cut off automatically. If you want to use the switch manually then it technically possible to do so
What should be electrical components for 150 watt metal halide lamp?
At the basic level, you're looking at: * Circuit Protection (fuse or circuit breaker) * Cabling * Mounting hardware (for the light fixture itself) * Within the fixture; A socket, bulb, bulb protection (cover, or sheild)
Is it in compliance with the National Electrical Code to install light fixtures with number fourteen leads to a thirty amp circuit?
Yes, Section 240.5(B)(2) Fixture Wires, allows #14 AWG fixture wires to be tapped to the #10 AWG branch circuit wires.
What if your ceiling light does not work although there is power to the live wire?
Is this a fluorescent fixture? Most fluorescents will not start if the fixture is not grounded. Make sure the fixture has the branch circuit ground wire properly connected.
You want to install a new light fixture in your bathroom upon removing the old fixture down you discover there is no grounding wire only a black and white wire and GFCI outlet on the circuit?
Just install the new fixture with black to black, white to white, and cap off the ground wire on the new fixture. It'll be fine.
What do you need to wire in a mercury vapor bulb?
The same procedure is used to wire a mercury vapour fixture as it is a normal home fixture. First the voltage source is needed and has to match the voltage that is on the nameplate of the mercury vapour fixture. The amperage of the fixture has to be taken into consideration, also taken from the fixtures nameplate. Once the amperage is known then the decision is whether one or more fixtures will be placed on the same circuit. When the total amperage is decided on, it will be that amperage that decides what size conductors will be used and what size breaker will be used to protect the circuit. Next decision is how you want to control the fixture. There are two methods depending on where the fixture will be placed. If it is outside then a photo cell with a bypass switch ahead of the cell is the most common configuration. If the fixture is an indoor type then just a wall switch will be used to control the fixture.
How do you wire the last fixture in a parallel circuit?
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
