I Suppose, need to choose a correct wire gauge for a lighting circuit, how to calculate it. Input load 12V Battery, load (two 100 W bulb), .Please clarify.
How to choose the correct wire gauge & size of a wire
Click For Summary
Discussion Overview
The discussion revolves around selecting the appropriate wire gauge for a lighting circuit powered by a 12V battery, specifically for a load consisting of two 100W bulbs. Participants explore methods for calculating the necessary wire gauge based on current requirements.
Discussion Character
- Technical explanation, Conceptual clarification, Debate/contested
Main Points Raised
- One participant inquires about how to calculate the correct wire gauge for a specific lighting circuit.
- Another participant provides a calculation for current by dividing the total wattage (200W) by the voltage (12V), resulting in approximately 16.66A.
- A suggestion is made to consult the National Electric Code for information on the ampacity of wires.
- It is noted that the wire gauge should be chosen to exceed the current it needs to carry, rather than being just under the required amount.
Areas of Agreement / Disagreement
Participants present various methods and considerations for selecting wire gauge, but no consensus is reached on a specific approach or calculation method.
Contextual Notes
There may be limitations regarding the assumptions made about load characteristics, safety factors, and specific application requirements that are not fully addressed in the discussion.
