Morphology
The phrase combines a named institution ('Board of Trade') with 'unit' (a measurement), so a learner who knows the words can infer it denotes some measurement associated with that body. However, the specific referent — that it equals a kilowatt-hour and is a historical/British energy unit — is specialized and not predictable from the constituents alone, requiring prior exposure or domain knowledge.
Etymology
Board of Trade unit comes from the British Board of Trade, the government group that once set rules for trade and services. They used this 'unit' to count electricity used by customers, so today a Board of Trade unit means 'one kilowatt-hour' on energy bills.
