In conflict

Published sources disagree on the power rating of Barista Express Espresso Machine (BES870XL), so the draw on any circuit cannot be settled from them. A reading from the rating plate is the only thing that resolves it.

What you must buy runs from $250 at the cheapest to $600 at the dearest. Every length on these bars is an editorial band bound, so both figures are ends of a range and neither is a quote. No item on these bars has a checked price, so every length is a band and no bar is a quote.

Figures are editorial budget bands, not live prices. A band is a range, so a build has a cheapest and a dearest version and both are shown.

operating clearance not established. Not one clearance figure exists for any item in this setup, so the region around each drawn item has no size, is not to scale, and cannot be measured against the bar. Where the plan is drawn is a packing illustration, not a recorded layout.

at most 796 mm of width left over: 1200 mm available less 404 mm of recorded envelope. Arithmetic on recorded envelopes only - no clearance is subtracted.

Open counter drawn to scale at 1200 by 600 millimetres. 1 item drawn from recorded envelopes: Barista Express Espresso Machine (BES870XL) 404 by 333 millimetres. Operating clearance is not established for any item, so the region around each one is drawn without a committed size and cannot be measured. At most 796 millimetres of width is left over: 1200 available less 404 of recorded envelope, with no clearance subtracted.

Product dimensions only - operating clearance not established

We hold the manufacturer's product dimensions for part of this setup, but a product envelope is not an operating requirement - it says nothing about the room needed to lift a water tank out, swing a portafilter or load a hopper. Until those are measured, this answer stays open rather than being estimated from the box figures.

Judged as a US 120V circuit under the US continuous-load rule (80% of the breaker rating).

Draw is computed from the manufacturer's own rating plate. The breaker figure is what trips when everything runs at once; the continuous figure is the code limit for a load running three hours or more, which an espresso shot is not. Both are shown rather than one, because collapsing them would either overstate or understate the risk.

What this check cannot see

Space is judged against the station's stated width, depth and height, using each product's envelope and whatever operating clearances are on record. The check does not see an obstacle inside that gap - a cabinet overhang, a wall bracket, a splashback lip - or anything you keep on the counter that is not part of this setup.

Electrical load is the sum of the products declared here against one circuit profile. It does not see other appliances on the same circuit that this setup does not declare, the condition of your wiring, or a supply outside the regime the circuit names.

Pairings are recorded one by one. A pairing that is not recorded reads Not established, which is not a finding that it works and not a finding that it does not.

What we hold, and where it came from

Every figure is marked with where it came from. A manufacturer or retailer number is a published claim, not a measurement; only “we measured” and “owner measured” are independent measurements. Operating clearances are the fields that decide real fit, and none have been recorded yet.
