cl447 tripping out?

replaced the heating element as it would only heat up on high dropped the back panel so all wires came off refitted as per previous threads all works but throws the trip switch on the extension lead on high in about 1 min and after about 10 mins on low not normally run on a extension lead but it has a trip out on it with wires coming off thought it would be safer anyone help please
cheers
