The way you calculate this is by looking at the amperage marked on the ballast of the fixture. Different size fixtures have different size ballasts. A 15 amp circuit is allowed to be loaded to 80%. 80% of 15 is 12amps. Now all you have to do is divide the ballast current into 12 amps and you have the total number of fixtures that you can added to the circuit.

How many watts does a 18 watt floresent light bulb consume?
Divide the wattage by the voltage. If it is 120Volt then the answer is .15Amp
How many Amperage for a gas stove?
A gas stove needs no high current. A basic 15amp circuit will suffice. Code will probably require a 20amp circuit since its in the kitchen.
How many 50 watt lights on a 15 amp circuit?
50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.
How many 40 watt regular lights can you put on a 20 amp switch?
You can safely put 48 regular (incandescent) 40 watt lights on a 20 amp circuit. If at some future date you might place higher wattage lights in the circuit, you will want to limit the number of lights to 20.
How many lights on 20 amp circuit?
Provided you use wire that is rated for 20 amps.
How many Stringing Christmas Lights can you put up before a fuse blows?
It depends on what type of Christmas lights. If they are the (now) standard 50 , 100, 150, mini-lights, they use a 3A fuse and you COULD use a MAXIMUM of about 750 lights if they are strung together from one string (end to end plugs) before blowing the fuse built into the plug of the first light set. If you plug them into separate outlets (or into an outlet-strip), then you could light about 3750 lights on a (otherwidse unused) 15 A household circuit. With the new LED type Christmas lights, it might be even more.
how many lights can go on one circuit?
You can find out more information on how many new fixtures can be put in a circuit by going to a home improvement store such as Lowe's or Home Depot or going to their direct website.
How many 150 watt flood lights can be on a 20 amp circuit?
The voltage needs to be known to give an answer to this question.
How many lights can you have on a circuit?
15 amps at 80% = 12 amps continuous. Watts = Amps x Volts.
How many 65w lights can be placed on a 15 amp circuit?
A 15a circuit can supply approximately 1650 watts, so 1650/65=25. I would stop at 20.
How many 20 amp ground fault interrupter circuit breakers are used to power the lights and receptacles for the medium shelter?
Two 20 amp ground fault interrupter circuit breakers are used to power the lights and receptacles for the medium shelter.
What could be causing the fuse for the dash lights to keep blowing on a 1988 Cherokee Laredo?
Short in the wiring. If you have a trailer wiring harness check it for frayed wires. The tailight circuit and the dash lights share a circuit on many vehicles. I hope this helps you. Mark
