Information
Definition
Power daisy chaining uses a supply arrangement where power is routed from one charger or connection point to another in a chained layout. It is normally assessed alongside phase availability, circuit capacity, protective devices, cable sizing and DNO/site constraints.
Why it matters
It can simplify wiring in some installations but must be checked against manufacturer instructions, protection requirements and UK wiring rules. For UK users, it affects installation cost, available charging power, protective device selection and how easily a site can be expanded.
