Looking for ideas, advice on the hookups for the espresso machine in the dining room.
Here is where it will go - on a table where that brown drop leaf table is now. It will be right next to the built-in that has the door ajar. I figure on bringing the power, water, and drain lines up through the inside of that built-in. I'll need 1) 240v circuit and receptacle, 2) 120v 15A circuit with standard household double outlet, 3) cold water line with pressure regulator and water filter (can be in basement below) and shut-off valve (either accessible from built-in, or also in basement), 4) drain line that will dump to outside garden.
1) is for the espresso machine. The machine draws max 20A (if all coils of heating element and pump are on). When starting from cold, it will draw 15A for about 1/2 hour. Any draw above 15A will be for a few minutes at most. I plan 10 ga copper THHN in PVC conduit up into the built-in. The run is about 50 feet from the sub-panel. I plan to use a 240V 30A GFCI breaker. I plan to put the electrical box and receptacle in the side of the built-in.
Question: the machine is older (1993) and has a three-wire cord. I assume I should run four wires and ground the receptacle. But I don't really want to try to rewire the machine to four-wire unless you guys think it's necessary.
Question: Am I making this harder than it needs to be? Is there some sort of jacketed 10/4 cable I can simply run through the joists, without bothering with conduit - or is that sloppy? The last 240V circuit I installed used conduit and 6 ga wire, because it is a 50A circuit.
Question: do I need to build some sort of separation inside the built-in to cover up the conduit and electrical boxes? I mean for safety or code reasons?
2) is for the grinder and just because you can never have too many outlets in an old house. I plan to simply connect this to one of the circuits for the basement's 120V outlets, at a handy box, with Romex through joists; Romex will be in conduit when it enters the built-in. The grinder will draw 1.5A. I also plan this receptacle to be in the side of the built-in.
3) is for the espresso machine supply. It wants 25 psi supply. Portland water is very soft but I want a filter anyway. There is a copper line to an outside hose bib, running along a basement joist about 10 feet away. I'm probably going to call a plumber to make the connection into the copper line. The machine uses a hose with a 3/8" (corrected) NPT fitting.
Question: should I have the plumber run copper line all the way to the built-in? I was thinking copper line to the pressure regulator mounted on a joist close to where the connection is, then something like John Guest flexible line and fittings from there. Mount filter in basement where it'll be easy to change, then flexible line up into built-in, then shut-off valve, then cut a hole in the built-in, flexible line exits and appropriate adapter to machine's supply line. Does this sound messy/sloppy? How would you do it? I feel slightly bad because the house has no plastic supply line anywhere, everything is copper, so feels like I'm being lazy/cheap.
4) is for the espresso machine drain. I want to simply dump drain water into the garden outside. The back part of the built-in is a "bump out" so I can simply cut a hole, run flexible line from machine to outside.
Question: Again, does this sound sloppy? I really don't want to connect to the house drain system with vent and all that rigomarole. This line is going to drain plain water with a little coffee, maybe a quart a week.
