Would you say fitting an isolator to the small plate with knockouts on an aircon unit.the small plate which is left when you take covers off.this is the outside unit .is it bad practice or acceptable

Hi davidanthony41. Your question would have been better off on a new post. Nothing to do with current carrying capacity. Get the mods to move it, or you would delete post 5 and start a new one.

As already mentioned, get the post moved or deleted and start a new thread. Also "a picture paints a thousand words".....
