Location; Single Family Residence, Los Angeles California. Please share your comments and repairs recommendation; Although I am not an electrical contractor or an electrical repair person, however, I am concerned about my friend' s house' s wiring method to supply 30A Dryer at the garage, via Flexible Metal Conduit. I am assuming this was done several years ago, however, I am concerned that wiring' s method, via Flex. Metal Conduit is unsafe for this situation and should have been done differently, both in selection of the conduit' s type and access to the service panel?
Yeah it looks ugly. Definitely not a professional installation, but there doesn't seem to be a code violation or hazard based on your pictures.
If it was done recently, then it's not to code because the installer put in a NEMA 10-30R receptacle (3-prong) instead of the required modern NEMA 14-30R (4-prong).
You can simply leave it as is and use it. Just make sure the copper bonding strap remains in place on whatever dryer you put there. They come with it installed by default.
