I am currently developing a heated food merchandising unit to be supplied from a 13A three pin plug.
If the unit is designed around 230V, 13A, do I have an issue when the supply voltage is at the top of its tolerance (230V + 10% = 257V).
As I have a purely resistive load, the current drawn would be 14.3A
Is this an accepted method or should the unit be designed around 257V 13A?
Your help would be appreciated.
