Is that possible to order long leads like that? My plan is to connect the longer wires via terminal block like this <a href="https://www.grainger.com/product/TEMPCO-TEMPCO-Ceramic-Terminal-Block-2LRU1?gucid=N%3AN%3APS%3APaid%3AGGL%3ACSM-2295%3A4P7A1P%3A20501231&gclid=CjwKCAjw9J2iBhBPEiwAErwpeSJJ1a72b0N9GsRysLKk3Ft4PQdkw5__V5cNCztLcIgSVrxe46dsaBoCjQUQAvD_BwE&gclsrc=aw.ds" id="LPlnk478143">https://www.grainger.com/product/TEMPCO-TEMPCO-Ceramic-Terminal-Block-2LRU1?gucid=N%3AN%3APS%3APaid%3AGGL%3ACSM-2295%3A4P7A1P%3A20501231&gclid=CjwKCAjw9J2iBhBPEiwAErwpeSJJ1a72b0N9GsRysLKk3Ft4PQdkw5__V5cNCztLcIgSVrxe46dsaBoCjQUQAvD_BwE&gclsrc=aw.ds</a></div>

If you have a better idea or can point me to a sufficiently high power heater with long leads please do. Perhaps we can custom order them? </div>

It's worth thinking more about the final design. I don't think we want to take every heater wire all the way out of the enclosure. We likely want to run a single larger gauge wire for each zone of ~5 supermodules that gets split into parallel connections to
each heater.</div>
