Increase wire size for voltage drop Mike Holt's Forum
8 hours ago Oct 27, 2011 . Massachusetts. Oct 27, 2011. #9. Hv&Lv said: Several electricians have told me that they increase there conductor one size for every 100'. I talked to one today that told me they were going to increase one wire size for every 75' to account for voltage drop. There aren't any calculations done, just an increase based on length.

Frequently Asked Questions
How to calculate the voltage drop of a cable?
Voltage drop Ampere/Meter which you will get from the cable supplier (in mV). Once you get all the above data, the voltage drop can be calculated as follows. Voltage drop= (voltage drop ampere/meter) x length x current. This will be in mV. Just divide by 1000 to get the voltage drop in volts. to the load (lighting, motor) should not exceed 5%.
How to calculate the load current of a cable?
Calculate the load current from the load data available. Formula is: The current obtained has to derated since the cable is designed to operate at a defined temperature. Derating factors will be available in cable catalog. Get the cable size corresponding to this derated current from the catalog.
What is the cable calculator?
Eland Cables' Cable Calculator can help you determine the most appropriate cable size for your installation against British and IEC standards. Complete the sections below to calculate your results.
How are cable size results calculated for international standard cable?
The cable size results for International standard cable are calculated from IEC 60364-5-52: Low Voltage Electrical Installations, selection and erection of electrical equipment – Wiring systems and are based on 230V and 415V voltage drop. In both BS and IEC calculations, the KW calculation is based on a power factor of 0.8.
How do you calculate voltage drop on a cable?
How to Calculate Voltage Drop. 1 Take the value from the volt drop table (mV/A/m) 2 Multiply by the actual current in the cable (NOT the current rating) 3 Multiply by the length of run in metres. 4 Divide the result by one thousand (to convert millivolts to volts).
What is the voltage drop of 70 sqmm cable?
Voltage drop of cable = 5.8% Here voltage drop for 70 Sq.mm Cable (5.8 %) is higher than define voltage drop (5%) so either select higher size of cable or increase no of cable runs.
Can you do electrical calculations on your mobile phone?
Basic electrical calculations on your mobile phone. App for complete DIY electronic calculations along with circuit images. Calculation of theoretical energy spending based on power used by appliances.
What are the conditions for selection of proper cable?
For selection of proper cable following conditions should be satisfied: Cable derating amp should be higher than full load current of load. Cable voltage drop should be less than defined voltage drop. No. of cable runs ≥ (Full load current / Cable derating current).
