Brad Ford Posted November 9, 2012 Posted November 9, 2012 I saw on richard holdmans site where he uses 20 amp fuses in his controllers instead of 15 amp. Does this make the controller 40 amp total? Or is this not a good idea and why? I'm needing to get as much power as I can out of a couple of my controllers......

Shubb Posted November 10, 2012 Posted November 10, 2012 The boards can handle 20 amps per side, but the incoming power cord is only rated for 15 amps. So in addition to replacing the fuse you also need to upgrade to a 20 amp cord.Don't forget the triacs are only rated for 8 amps per channel with the high power heatsinks.Scott
gtoyeah Posted November 10, 2012 Posted November 10, 2012 Sorry, The link did NOT work for me? Is this an item I can purchase locally?
Brad Ford Posted November 13, 2012 Author Posted November 13, 2012 Scott, can I get the cords from lor or do I need to go elsewhere?
Shubb Posted November 13, 2012 Posted November 13, 2012 I think LOR only carries the 15 amp. You can pick them up locally, HD, Lowes, ect.You might have to buy a 20 amp extension cord and cut the female end off.All mine are hard wired with #12 wire so I didn't have to hunt down the cords.Scott
Brad Ford Posted November 13, 2012 Author Posted November 13, 2012 Ok, I've got some ideas. If I buy that heavy a extension cord that could get a little pricy....especially knowing I'll be cutting them up lol. Thanks for the info!
Brad Ford Posted November 14, 2012 Author Posted November 14, 2012 One more question. I found some fuses at radio shack but they say"20amp 250 volt" is this what I need or is it something different? They are ceramic.
Shubb Posted November 15, 2012 Posted November 15, 2012 If they are they same physical size you're good. Most fuses are rated for 250 (or less) and 600 (or less)But they are not interchangeable in the fuse holder.

Or any solid wire? If so how did you make the connection?
Shubb Posted December 17, 2012 Posted December 17, 2012 Mine is a little different than most since it is permanent.I hardwired using #14 Neutral and #16 Hot to separated 115 volt outlets mounted on gutter boxes.Then SPT-1 cord goes outside to the displays. The other half of the controllers are mounted in custom enclosures that hold 4 controllers each and run straight to the display elements.
