    How do you live test an off peak CU ?

    I've changed an off peak CU that had fuses in it to a board with Mcb's . does anyone know how to get around the problem of there being supply only at off peak time or would it be permissable to note it in limitations ?

    Off peak supply

    Can I get away with this? Did a board change and left two economy seven heaters RCD unprotected. Power supplying them doesn't come on until 00:00-06:00. Just two radials each rated at 16a?
