At that distance the current would be limited by the acceptable voltage drop. As the load consists of lights a 3% drop should be the starting point, which means a voltage drop of 4.5 volts. 700 ft of 16-2 wire (copper) has a resistance of 1.4 ohms therefore the current allowed is 4.5/1.4 amps or 3.2 amps.
The total power is 150x3.2 watts, or 480 watts, so the number of lamps is 480/7 or 68 lamps.
What else can I help you with?
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What size wire do you use and do you need a 240 volt sub panel to send power to some lights and a 1500 watt 120 volt heater about 400 feet away?
For a 1500 watt 120 volt heater located 400 feet away, you would need to use at least 10-gauge wire to minimize voltage drop and ensure efficient power transmission. It is recommended to install a 240 volt sub panel near the heater location to account for the distance and potential power requirements for additional lights or equipment.
Can you run a 60 watt light bulb on a 300 volt wire?
If your light bulb voltage rating is under 300 volts then yes it can use 300 volt wire. The voltage rating of the wire is the maximum voltage that the wire can safely carry. The three common insulation groups is 300 volts, 600 volts and 1000 volts.
Can you use armored cable to wire 277 volt lights?
Yes, armored cable can be used to wire 277 volt lights. However, be sure to select the appropriate type and size of armored cable rated for the voltage and current requirements of the lighting system to ensure safety and compliance with electrical codes and regulations.
What size wire do you need to run 4 1500 watt 240v lights spaced out over 200ft span?
10 gauge will suffice.
What is the recommended wire size for a 220 volt circuit according to the 220 volt wire size chart?
The recommended wire size for a 220 volt circuit according to the 220 volt wire size chart is typically 10 gauge wire for a circuit with a maximum of 30 amps.
Will 14-2 wire accompdate 2 1500watt baseboard heaters 240 volt?
No, 14-2 wire is not suitable for two 1500-watt baseboard heaters on a 240-volt circuit. Each 1500-watt heater draws approximately 6.25 amps, totaling about 12.5 amps for both. However, 14-gauge wire is rated for a maximum of 15 amps, which is close to the limit and does not provide a safe margin. It is recommended to use 12-gauge wire, which is rated for 20 amps, to ensure safety and compliance with electrical codes.
Need to wire for a trailer on a 2005 Nissan Quest don't know which is stop and turn signal wires there are 3 wires to the same bulb one for tail lights one for stop light.?
get a 12 volt tester light and turn the lights on and poke each wire until your tester light lights up and then you'll know what wire you need.
Can i use a 8 gauge 1200 watt power wire for a 1000 watt amp?
A #8 conductor is rated at 40 amps. Wattage is the product of amps x volts. As you can see the voltage is needed in this question to answer it. In the electrical trade I have never come across the terminology watt amp. Volt amp, yes.
What wire size is used for 100 watt 12 volt lamp?
For a 100 watt 12 volt lamp, you should use a wire gauge size of at least 18 AWG to ensure it can handle the current without overheating. It's always best to refer to the manufacturer's recommendations for the specific lamp you are using.
How do you wire a Christmas light to a switch and 9 volt battery?
i wld like to put lightson my motorbike but lights r 240v and bike is 9v how do i do it
Is a 230 volt motor cheaper to run than a 115 volt?
Yes, a 230 volt motor is generally more efficient and cheaper to run compared to a 115 volt motor. Higher voltage motors are more energy efficient because they draw less current, resulting in lower energy costs over time.
