"Now" is Elexon's 5-minute figure for each cable: positive while power comes into Great Britain, with a minus sign while it goes out. Capacity is each cable's rating in either direction.
What the interconnectors do
An interconnector is a high-voltage cable, nearly always under the sea, that joins Britain's grid to a neighbour's. Power can flow either way, and which way it flows is set by the electricity markets at each end: it generally flows towards whichever side's price is higher. So Britain tends to import when its own wind is low and the continent's power is cheaper, and to export when its wind farms are producing more than it needs. Imports count as one slice of GridMonkey's live pie; each cable's own page shows which way it is flowing now and over the last week.
The cables to France, Belgium, the Netherlands, Norway and Denmark connect to the continent's grid. Moyle runs from Scotland to Northern Ireland, and East West and Greenlink run from Wales to Ireland: the island of Ireland has a single electricity market of its own, so all three trade with it.
