| Feb 21, 2020 at 5:11 | comment | added | user154046 | Sounds good. Would I be able to use electrical tape to insulate them, or should I be using something different. | |
| Feb 21, 2020 at 5:10 | comment | added | Jasen Слава Україні | unwind the secondary an put several strands in parallel to make a rope with about 10 square millimeter total cross section. that's about approximately a square with 1/8" sides | |
| Feb 21, 2020 at 5:07 | comment | added | user154046 | Would the temperature issue be resolved by a cooling fan? At least enough so that I could get away with using electrical tape for insulation on the 8 AWG copper wiring. Thank you. | |
| Feb 21, 2020 at 5:06 | comment | added | Jasen Слава Україні | magnet wire is preferred becase its insulation can handle higher temperature than PVC insulated wire. and because it's more compact | |
| Feb 21, 2020 at 5:05 | comment | added | user154046 | Unfortunately my transformer is relatively urgent and I don't think that I'll have enough time to get it shipped. Would the 8 AWG copper wire on the secondary allow me to produce the needed 6.3 V and 25 A? Thank you. | |
| Feb 21, 2020 at 5:02 | comment | added | Jasen Слава Україні | magnetwire.biz/magnet_wire_current.html only good for 24A use two in parralel. | |
| Feb 21, 2020 at 5:01 | comment | added | user154046 | Moreover, would I be able to change to a 24:7 winding, where the 300v 18 AWG wire makes up the primary and the 7 turns come from the 8 AWG copper wires on the secondary? Due to the number of turns, the primary will also likely have wires layered on top of other wires. | |
| Feb 21, 2020 at 4:57 | comment | added | user154046 | Will normal 8 AWG copper wire work for the secondary? Thank you | |
| Feb 21, 2020 at 4:50 | comment | added | Jasen Слава Україні | thats only for contact between turns of the secondary, it's ok to use stranded wire for the secondary so long as each turn of the secondary is insulated from the other turns. | |
| Feb 21, 2020 at 4:48 | comment | added | Jasen Слава Україні | bare wirwes must be insulated (must not touch), the wires used in the original secondary have a clear insulating coating on them, this type of wire is called "magnet wire" | |
| Feb 21, 2020 at 4:47 | comment | added | user154046 | Is it acceptable for bare copper wires carrying 6.3 V to be in contact with each other in the secondary? The insulation may be too thick for my MOT. I'm planning to wrap it with electrical tape, but there might be some copper wiring that finds its way to another strand. | |
| Feb 21, 2020 at 4:45 | comment | added | Jasen Слава Україні | if you twist many strands in parallel to make a rope it would be able to carry 25A, be sure that the ends of each strand are fully soldered | |
| Feb 21, 2020 at 4:42 | comment | added | user154046 | Would the secondary wires for a MOT be able to handle the 25 A current? Thank you. | |
