I'm installing a new coffee bar and plumbing a dual boiler E61 espresso machine and want to run it in 20-amp mode. I've installed a dedicated 20-amp circuit with a single dedicated 20-amp outlet installed under the sink in the coffee bar. Since it is under a sink, the outlet is GFCI. I've outlined this outlet in green marker (see attached picture).

I do not want to add any outlets or switches, external hubs, or overly expensive controllers in the chain. The Legrand system and additional hub needed for example is of no interest. If that is the only solution, I will continue to turn it off and on manually and wait the 30 minutes or more for the machine to warm up.

The only viable option I have found so far is the Intermatic HB110 Series 20 Amp Air Conditioner and Appliance Plug-In Timer. It only has a single plug and I planned on plugging my grinder in as well, plus it would be on the bottom of the Intermatic and the way my outlet is wired it could block the additional 20-amp outlet installed below it.

This additional 20-amp circuit outlined in red marker in the attached picture has a second outlet on the circuit with the primary purpose of providing power to the entertainment components in the adjacent family room. It would also be used to plug in the rug beater when using the central vacuum that we now need to access under the sink with the new coffee bar covering the wall it was on. I needed to move the vacuum outlet over a bit in the wall for clear access. I could probably plug the grinder into this circuit without issue.

I do have a Furman CN-20MP Remote Duplex Power Sequencer I'm not currently using. I assume there are simple timers that could send a 12v on/off signal to the Furman CN-20MP? The timer could be 15 amp or even battery powered as long as it can trip a 12v on/off relay.

Thanks.

I've been using this for a few years:

25amps, has a button, but also an app for scheduling.

Did you install this and does it require any additional components/controllers?

I only see 4 wires. My dedicated circuit and single outlet has 3; Hot (Black), Neutral (White) and Ground (Bare Copper).

I could get access to the 12/2 wire run in the crawlspace beneath the coffee bar. Not convenient when needing to reset and pair. Would I just splice the POWR3 in-line with the Hot and Neutral and leave the ground running strait through to the outlet? Thanks.

The 2 whites got to the "N" terminals, L In connects to the black supplying power and L Out to the black going to the machine, the ground do not connect to the device, just gets left alone.

I used one of the HB110 timers briefly to run my Bosco. The timing was all over the place. Replaced with their ET1705C. https://www.zoro.com/intermatic-electro ... /G1796733/ At the time they sold for 40% of the current price.

The Sonoff POWR3 would be wired stand alone as below, without any additional controllers or hub required? Thank you.

I just got a 3ft 12gauge extension cord and spliced the unit in the middle.

The ground just bypasses the switch.

Do you mean wiring between the outlet and the breaker?
I don't know enough to say if that would be up to code. I placed it inline between outlet and machine.

Yes. It is getting crowded under the sink but a short, spliced 20-amp extension cord looks like a reasonable and likely better option. I prefer not to purchase from Chinese companies if possible though, especially WIFI enabled devices. Not judging, just my preference. Thanks.

There has to be a simple timer that can send out a 12v closed/open trigger that turns power on and off that I could use with my Furman.

I just wired in one of those old-school heavy-duty timers in a junction box before the outlet. It was easy because the wiring ran through the basement ceiling, so I just mounted it to the floor joist and the output wire ran up to the outlet. Time was plenty consistent.
