| Standard electric kettle as a DC dummy load ? |

| Doctorandus_P:
Some length of lacquered ("enameled") copper wire in a bucket can serve as a temporary quite nicely. MikesElectricStuff did a youtube about that some time ago: |

As far as water heater elements, I use 2,000W 120V that are about 7.5 ohms (regardless of what they are stamped) for heating water at my off grid home. There are "DC" elements for solar use that I believe are at least 300W at 12V, could even be 600W. These are more expensive. I bought two 2,000W elements for $15 shipped. |

If I needed a quick and dirty load for 100 amps continuous, I'd use a pair of heavy duty jumper cables, a bucket of water, and some resistive material. I might try hardware type steel wire or something. I probably will test the setup OUTDOOR and have a quick way to disconnect. That's enough power to cause some serious issues. |

Murphy's Law states you will burn up the coffee pot, and after paying to replace it you will be back where you started, minus xx.xx dollars (last coffee pot I bought was $60) and still without the components for a proper load. Take some of the coffee pot money and buy some components to make a safe and durable load. You will probably need it again someday. |

when i was a kid , I boil resistors in the water , metal can ... :) Now i get a bit older and build a primitive electronic load .... trouble with the load unfort. it I=const , sometimes need R=const. then measure the noise for example so I bought like this with diff nomination: https://www.aliexpress.com/item/-/32876339506.html with small heatsink, and in the water it can handle up to 200-300W per a single resistor heatsink like this https://www.aliexpress.com/item/-/32827258255.html was on ebay much cheaper ... hope it helps ... |
