WebOct 28, 2015 · 2. In order to limit the current drawn from a 120v socket to 15A using ohms law, you make sure that the load you attach has a resistance of at least 8 ohms. However when you buy a kettle or toaster, it doesn't tend to say 'resistance 8 ohms' on the specification plate, it says '120v 15A'. So the simplest way to limit the current is to make … WebFeb 11, 2015 · KY. Feb 9, 2015. #1. We had a contact resistance (micro-ohm) test on an 800 Amp thermal magnetic breaker,with a test current of 10 amp. The results were. Phase. A = 79mOhms (Line to Load) through the closed breaker. B = 115mOhms (Line to Load) through the closed breaker. C = 95 mOhms (Line to Load) through the closed breaker.

How to measure the Contact Resistance of a Circuit Breaker

WebOn-resistance is defined as the total measured resistance from the VIN to VOUT pins of the load switch. As load current (ILOAD) passes through the device, this resistance causes a voltage drop in the power path. The relationship between RON and the voltage drop (VIN – VOUT) is shown in Equation 1: (1) WebResistance R (Ohms) = 0.4, Inductance L (mH) = 3.55 Nonlinear Load: ... Breaker resistance Ron (Ohm) = 0.001 3. RESULTS AND DISCUSSION The Simulink model is set for execution for a period of 1 second.
