RE: DC fuse & circuit breaker questions crshears (Electrical) 15 Nov 18 13:25 Rule of thumb where I worked years ago was that provided the current trip setting was the same you could use an AC breaker rated @ =/> 2. Remember the fuse and breaker are there to protect your cabling from overheating (and potentially catching fire). Note! - in the calculator above FLA is RLA + 25%. Calculating the configuration fuses for microcontrollers is always a pain. This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. Com Whenever you are wiring power cables for a DC appliance in a RV, whether it be re-wiring your brakes or adding a new new stereo system, you need to understand that the characteristic of DC wiring is that you will encounter a voltage drop along the wire. The calculation assumes uncoated copper or aluminum conductors operating at the temperature selected and is based on the ac/dc resistance or impedance from NEC 2011 Chapter 9, Tables 8 and 9 for stranded conductors operating on a DC or AC 60Hz system. Starting Current, sometimes abbreviated as I start. Use a calculator to divide the number of watts by the voltage. 5 and 9 volts As led forward. Converting watts to amps can be done using the Watt's Law formula, which states that I = P ÷ E, where P is power measured in watts, I is current measured in amps, and E is voltage measured in volts. Click here if you have any questions or comments. 5 A with an input of 13. Your Benefit. Bussmann Fuses products are manufactured by Eaton Corporation. Therefore two 7. Choosing the right wire size for your DC electrical project is important, since a wire that is too small can overheat and possibly start a fire.
