No disagreement there from me! I won't say it's wrong to over-size house wiring either, I just don't agree that it adds anything to the quality of the install. That said, I totally agree that one should calculate or measure the voltage drop for headlights and upgrade wiring as needed. That just happens to be the chart I use, it might be wrong. 87 volts, based on 0.9989 ohms per 1000 feet from the chart I posted the link for. Also, I calculate the voltage drop at 25 amps and 24 volts over 35 feet of 10 Ga. 600 watts of headlights is a lot of lights. My high beams are way under 300 watts total, probably 260 watts (65 watt halogen times four). 24 volt headlights drawing 25 amps would be 600 watts of headlights. Headlights aren't what I thought we were talking about. explorist.I was saying that voltage drop on LED light runs and 1 amp fan runs are inconsequential. triplex is pretty expensive for 30ft so trying to reduce cost.Īlso need to know what size breaker for the inverter to ac distribution. explorist.life suggested 10awg triplex from shore power to inverter and 6awg from inverter to ac distribution with a 3000W 12V inverter but I assume I can go smaller since I am using 24V. Example: Your system will draw 20 amps and the wire length from the voltage source to the SCM-PD+. ![]() Most importantly, I don't see any recommendations for triplex wire size from shore power to inverter or ac distribution to inverter. See next page for 24 volt system wire gauge sizing chart. As in most electrical situations it is important that you know the maximum amp draw of the device being installed. Wire size by gauge, ampers draw and maximum feet of wire. We have a chart for 12-volt, 24-volt, 36-volt, 48-volt and 72-volt applications. Could I just use 10awg for everything from busbarconverterdc block since I already have it prewired and have excess 10awg wire?Īre all the fuses listed, besides the shunt fuse, ANL or MEGA fuses?Īre the 30A fuses listed from converter to dc block actually fuses or breakers in the dc block? Don’t worry, calculating the wire size is made easy with the wire size guides below. I have a preinstalled solar setup on the RV and 10awg wires are already routed to the battery from dc block. Just a couple questions to clarify everything. How to calculate voltage drop, you ask Download our mobile. I have edited the explorist.life diagram to suit my setup for reference.Įverything else that has not been whited out I am using in my system except I am replacing the bmv-712 with a smartshunt.Ģ4->12V converter will be added for dc block.Īny tips or constructive criticism outside of the scope of my questions is welcomed. Southwires Voltage Drop Calculator is designed for applications using AWG and KCMIL sizes only. Note: cable size is specified in AWG which stands for American Wire Gauge. Sorry for all the questions but this is all I have left to figure out and would love to get it all sorted out so I can buy all the wiring/fuses necessary. For example: 18 gauge, 16 gauge, 22 gauge, etc. Use a thicker gauge wire (the lower the number, the heavier and thicker the wire) between the 12V-24V driver and the light. Is 4/0 necessary from lynx to inverter, chassis ground, and batteries? (Answered: 1/0) Watts Enter the numeric value of total watts used in. Is 2awg from SCC to lynx correct for my system? (Answered: 4awg) 24V, we recommend increasing wire gauge or reducing wire length. What gauge wire from lynx to 12v dc block? (Answered: 10awg) CCT/RGB/RGBW For determining minimum wire gauge requirements based on wire lengths. What size ANL fuses at each connection in lynx distributor? (inverter, dc block, scc) (Answered: Inverter-250A, scc-150A, dc distribution-inline fuses)įrom shore power to inverter: What size triplex wire? (Answered: 10awg Triplex) On the chart below, locate where the wattage of your LED run intersects with the distance to your power supply. RV is about 25 feet from inverter to breaker and from shore power to inverter so I would like to get 30 ft wire for clearance ![]() I am following the explorist.life diagrams and videos as well as various other resources (Will Prowse of course)įrom Inverter to Breaker box: what size triplex wire? what size breaker in ac distribution panel? The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. I need some help figuring out wire sizing and fuse/breakers needed at a couple points in my build and haven't been able to find too much information relating to 24V systems. Telephone wire is typical AWG 22, 24, or 26. I have a 2022 Grand Design Transcend Xplor 231RK travel trailer (non-motorized) I am currently in the planning and buying phase of my solar upgrade on my RV. Hello everyone, this is my first post on the forum.
