Re: [EVDL] Schneeveis battery load (was: Testing Leaf Modules)
You might like to run heavy gauge wire to the bucket and the thinner resistance wire entirely in the water. The insulated wire may melt outside the water.

Re: [EVDL] Schneeveis battery load (was: Testing Leaf Modules)
With this type of load, remember that the rod or pipe is electrically live. And so is the water that touches it! I like using a coil of insulated copper wire, dunked in a bucket of water. The wire can be considerably undersized for the current listed in a wire table -- we *want* it to have excessive voltage drop and run hot. the water keeps the insulation from melting. -- Excellence does not require perfection. -- Henry James -- Lee A.

Re: [EVDL] Schneeveis battery load (was: Testing Leaf Modules)
The simple way to make a clamp and not needing to machine anything is to use a copper strip (cut from a sheet of copper or a thin bus bar) that you can wrap around the pipe and only one bolt is needed to make this into a clamp that always fits.
