Box is likely grounded, but better practice is to bond it to the ground. The steel armor and box are conductive, so it's grounded that way. Also the ground screw on receptacles also have continuity to the metal parts that screw the receptacle to the box, so there is a ground present even in the absence of a ground wire, in that case. But always use the ground wire and always bond it. Also use the top and bottom screws and a nut. The center screw can come loose, and also the pressure of plugging things in can weaken the outlet and wear it out prematurely.

That's right. It is a code violation to install a receptacle to a cover the way it is is done in this video. NEC 406.5(C)

Best practice is to use the two provided 6 - 32 screws to attach receptacles to metal cover rather then only the center screw that usually comes loose. After cutting Type AC or MC cable cut the sharp edge at a 45 degree angle then install red anti short bushing.

Should you be doing a jumper from the ground to the box so the box is grounded also since it is a metal box fastened to a metal building?

I understand that the socket should be grounded to a metal outlet box. However, I've also read that you can never ground to the structure. So what should be done when using a metal box on a metal frame??

That outlet should be grounded to the metal box as well

As an electrical guy, I know that videos are there to inspire. Please do not take them as a step by step instruction as the code allows each building department (Jurisdiction) to adjust (interpret) the code as written. Many commentors pointed out several code misses: 210.8. Gfci for homes puts "out buildings" under garage requirements. 547. Is for "AGRICULTURAL BUILDINGS" with wiring method restrictions based on the animals kept there. Anyone can put a wire under a screw, but which screw is where the money is made. You can learn and do yourself, but calling the building inspectors or a local guy that just did that same job last week might get you a solution to a problem you never knew you had.

Smart using type MC cable that has a insulated copper real deal ground conductor verses the flimsy #16 or 18 guage aluminum wire that's inside type AC ( BX ) cable. You should have use a ground screw to ground the metal box. Extremely dangerous if the two 8/32 screws come loose or fall out then box is not grounded.

Well yeah, everything is easy

Um, no ground to the box?? That ground wire should be attached to the box, not the outlet, and a grounding pigtail attached from the box to the outlet grounding screw.

You first need to ground your box then your plug in

I assume that the box is grounded by the mc, but you should use the ground wire to ground the box and there is no need to attach a wire or pigtail to the receptacle. When the receptacle is mounted to the cover and the cover is mounted to the box everything is grounded. The receptacle has a self grounding strap on the lower yoke. The cover comes with screws and nuts to mount the receptacle securely and you didn't use those. The screw connection between the receptacles becomes optional. The 20 amp receptacle is ok, but unnecessary, a 15 amp commercial spec grade would be my choice, 15 or 20 amp circuit, it doesn't matter.
