The circuit is likely rated for 15 amps. The building code usually says not to use more than 80% of the available amps, so you have 22 usable amps. (Ontario building code, but representative of most North American building codes.

LED lights use a ridiculously low number of amps. I calculated at one point that each LED light in a set I was looking at used 66 miliamps (0.066 amps) ... which means 12amps divided by 0.066 amps per LED ... or 182 LED lights on a 12 amps circuit.

Lol. When moved in, my kitchen had TWELVE 5000K 48" Fluorescents. It's not a large kitchen either, maybe 10' x 14'. I immediately removed all but two and it was still ridiculous until installed 3200k down cans shortly after. I think some people don't want to admit that their eye sight is degrading so they just put more lights in.

Reply to comment by nixiebunny in Proper use of ball bearing for a vertical rotation (azimuth rotation for a ground station) by Fun-Palpitation81

Thank you, for my elevation stepper, I am using two rolling bearings, directly driven by a stepper - I'm using direct drive to save on space, but if I haven't tested that I'll have enough torque.

For the azimuth drive, I will try using these slew bearings, with the benefit that I can feed my elevation stepper motor wires through the center.
