The standard voltage in the UK is 230V (with a permissible range of 230V ±10%), and the rated current of the socket is 13A.
Therefore, the theoretical power is:
230V × 13A = 2990W (approximately 3kW)
In other words, mathematically speaking, the theoretical maximum load power of a 13A UK socket is approximately 2990W.
