If I change my cooker do I need to get a electrical safty certifiate thingy to say its been installed correctly?
(The circuits already in just taking old one out and replacing with a new)
The actuator (its an MSV322/19) on my flowsure has died. It has only two wires (a live and neutral). Can it be replaced with a ACT322 which has four wires and if it can where should they be connected?
