A Russian P&ID often closes a load's text with the panel it is wired to:
'... кВт' on one line, then 'к CP1' ('to CP1') or 'к щиту CP-2' ('to
switchboard CP-2') on the next. wiring_target knew 'подключение к ...' but
not the bare preposition. On the field P&ID most loads therefore had no
panel and no measurable cable.
The preposition к / ко now counts when it is a whole word and the panel is
the next word, optionally after щиту / шкафу / панели. The к of кВт is
never read as the preposition. The new test failed before the change.
