This category only includes cookies that ensures basic functionalities and security features of the website. In conventional home electrical systems (120/240 volts ac), wire is sized primarily for safe amperage carrying capacity (ampacity). B-K Lighting provides the lighting profession with the highest quality, most innovative, fairly priced lighting fixtures and services available. These cookies do not store any personal information. Wire Runs; The way the lines are run has a big impact on the performance of the system and influences the way power is distributed. Cable Distance & Light Power Settings. The overriding concern is fire safety. This convenient calculator allows you to customize the different aspects of the system such as wire gauge and run lengths between fixtures. One of the most important aspects of designing and building any part of a vehicle electrical system is determining the correct size and type of cable to use for each circuit. OUR OFFICES WILL BE CLOSED: Friday January 1st for the New Years Holiday! What is Voltage Drop? Low voltage lighting allows for small fixtures, efficient lamping, and safe installation and adjustment. B-K Lighting provides the lighting profession with the highest quality, most innovative, fairly priced lighting fixtures and services available. The calculator will alert you if the wire size is too small to handle the wattage (load) of the lights. Cable Options. This Cable size calculator helps you find the exact size of your cable/Wire needed along with voltage drop and much more. Another common method of wiring is known as the “loop” method. Calculate. This is a calculator for the estimation of the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current. Allowable Voltage Drop – The calculator allows entry of a voltage drop, but caution should be used when doing so to make sure you are calculating the wire … If for example you have a 12V TV that is rated at 60W, then you can either calculate this is 5A, or you can adjust the current until the watts is close to the value you want. If you continue without changing these settings, you consent to this. To use the calculator, enter the Maximum Current in Amps of the circuit, and the Length of the Wire, and operating Voltage. At the top of the column above your wire length is the minimum wire size (gauge) to use. As a professional landscape lighting designer looking to install and operate a new low voltage lighting system, you need to consider what transformer will be required to convert your standard line voltage outlets using 110-120V into your outdoor low voltage 12V-15V lighting design. Wire Gauge The Voltage Drop Chart also contains a handy conversion guide from the metric wire system to American cable gauges. We recommend 12-gauge or 10-gauge wire for long Transformers generally range from 150- to 900-watt capacity. To use the calculator, enter the Maximum Current in Amps of the circuit, and the Length of the Wire, and operating Voltage. These calculations are similar except amperage levels, wire sizes and run distances are much lower.  Some examples of interior accent lighting with lower load calculations are undercabinet lighting,  display cabinet lighting, art lighting and cove lighting fixtures.  If you’re interested in learning more interior load calculations or need design advice or assistance with your lighting design plan, please let us know and we would be happy to assist you. Low voltage landscape wiring or electrical cable comes in several numerical gauges or sizes. Low Voltage LED Lighting Transformer Calculator: Enter units of product and conversion is made to show amount of transformer capacity used. Put the necessary values and click on calculate to see the result . Our low-voltage landscape lighting calculator will allow you to enter this information to determine the maximum distance from the transformer to the lights. 3 - Enter max amps to be carried by the cable [amps = watts / voltage]. About the only electrical code restriction for a low voltage system is that the transformer be connected to a GFCI protected receptacle or circuit, when installed in locations that require GFCI protection (see Common GFCI Location Requirements ). B-K Lighting, Inc. - Low Voltage Calculator Products Total Length of Wire Run x Distance to Point of 1st Connection = Voltage Drop Cable Constant. Introduction. 3) Choose A Power Supply To figure out which power supply is best, consider two things: the total wattage of the lights that you’re purchasing and if you anticipate adding lights in the future. Transformers generally range from 150- to 900-watt capacity. The loop method brings the same voltage and power to both ends of the wire … A lower number means thicker wire and greater capacity to carry the power current for longer distances. The Voltage Drop Calculator will determine the correct THHN wire sizes for recommended 3% or less drop in voltage for each circuit based on the specified wattage.
