None of the stuff you'll make has UL or NEBS approval unless you pay
for that. I'd be inclined to suck it up and pay for remote hands to
turn a switch unless you own the colo or they're casual enough that
they don't care (your insurance company might though).
Should you decide to go ahead and bu
For larger DC devices with ~50amps per side, does anyone have a software
accessible way to turn off power?
I've looked into PDU's but the ones I find have a max of 10amps.
I've considered building something with solenoids or a rotary actuator
that would turn the switches on or off, but that's

Not quite remote-hands cheap, but worth every penny in a pinch.

The rotary actuators are an off-the-shelf item for transfer switches. No
problem to get them paired with high-amperage switches. But a contactor, which
is a solenoid-driven switch, is also an off-the-shelf item. The ones I use in
EV applications are rated for 1000A, and cost about $300. You n
