I realize this may be super simple but i cant for the life of me figure out how to open a wall mount transformer it seems like they are snapped shut with no way to open?
Transformers are not usually made to be opened. There is usually no point. There is nothing inside but tightly packed bundles of copper wire coated with something. They are repairable easily in a shop that knows about the design of that particular transformer. They know how to open them, but there is usually no way for a user do it. Mayan
Are you looking for the connection cover or are you attempting to dis-assemble the transformer? Connection covers: There is usually 2 connection covers on transformers - Input and Output - not always marked. If this is actually a ballast (a special transformer) it often has only one cover and is likely sealed and tar/oil filled Dis-assembly: If you are attempting to dis-assemble the transformer, it is harder than it looks. Depending on the size, age, manufacturer, KVA, voltage, usage, etc of the transformer; some are sealed with a pitch, others are oil filled. As was stated in an earlier answer, they are built not to open/dis-assemble easily. A transformer consists of many steel plates sandwiched together with wire (Older is copper, newer may be copper clad aluminum) wound around them in specific patterns.
Never attempt to prise apart sealed units.There is a risk of explosion.
They are glued, or even sonically welded. They are made to be replaced not repaired. They can be open by sawing a knotch in the corner and prying open with a screwdriver.
I would ask you why you want to open the transformer? Are you salvaging it or are you just curious? Inside the brick as these transformers are commonly referred to, is a small electrical transformer. If your brick has AC output, that's about all you will see. If it provides a DC output, you will probably find a full-wave, bridge rectifier module in addition to the transformer. By the way, there are no user-serviceable parts inside. These bricks are considered disposable and therefore, are snapped shut, and/or ultrasonically or heat-sealed at the factory.
