My landlord (of a barn I rent) added a 220 and a 110 circuit for me.
He ran one conduit from the panel to a j-Box. In the 4-gang box he
added a 220 plug of the type I requested. I can see two hots and a
ground wire all connected to the plug. No ground to the box.
There is also a black and white wire wire-nutted off that he tells me
is my 110 circuit. I want to pull armor cable or romex from that j-box
to a 4 gang 110 outlet, then to switch some lights, etc.
Questions:
1. Should the 220 plug be grounded by pigtail to the box also?
2. How do I properly ground the romex or armor cable I pull from this
box for the 110 circuit?
- I though maybe ground to the box but was told I need a ground
back to the panel
- Do I pigtail from the ground on the 220 plug?
3. If I add some conduit and a second 220 plug in another box do I
just run the three wires to the new outlet with no ground wire
pigtailed to the boxes?
4. Will I die and should I hire an electrician?

I would recommend to check NEC code for grounding section. it should
give you some instructions. if you are not sure by yourself, always
ask Electrian for help.
If you can not find proper page from NEC code, I can help you with
that

Have the landlord make the changes.

totally up on changes to code or maybe even old code.
This is what he should have pulled for the two circuits
220 2 hots (black, red), 1 neutral (white), a ground (green)
110 1 hot (color), 1 neutral, a ground (I'd probably share the 220
circuit's ground)
I'd probably install a multi-circuit sub panel via a 4 wire feed &
local ground rod but I digress ..........
With the arrangement noted above you're all set up to use:
old school tools 3 wire (2 hots & ground)
newer style 4 wire (2 hots, neutral & ground)
A few questions
So the wires for the 220 circuit are 2 colored & 1 green?
>>>220 receptacle of the type I requested<<<< 3 prong?
Conduit size & type (plastic or steel)?
Boxes? (plastic or steel)
If there is a green wire back to panel, is it connected to the ground
bus?
if the boxes are metal, they need to be bonded to the grounding
conductor.
>>>I though maybe ground to the box but was told I need a ground back to the panel<<<< by whom?
Shut off both circuits, make sure they're dead and that no one can re-
energize while you're working.
Can you see the panel from the barn?
Remove the ground wire from the receptacle and "pigtail it";
that is, using a wire nut connect 3 short ground wires as follows:
1 goes to the 4 gang box
1 is available for your 110v extension circuits
1 goes back the 220v receptacle
If oyu're going to extend the 220v circuit to feed another box, you'll
have to get LARGE wire nuts to handle your ground wire cluster or do a
multiple pigtail arrangement. Same would go for your 220v hots.
By now, considering there is also a 220v receptacle in your 4 gang
box, it'd getting pretty crowded.
How many tools are you going to be running? Is 1-220v & 1-110v circuit
enough power?
Keep an eye out on Craigsist for a Square D (QO) sub panel.
New they are very expensive, used much cheaper.
Wayne, Rico....... how'd I do? :)

I prefer Square D QO style panels & breaker but for a barn & for $40
their "Homeline" brand is probably good enough.

a great solution for a minimum investment.

Sounds like improper wiring.
I would think that you need for the 220
a black and a red and a white and a ground.
for the 110 circuit
you should have a black and a white and a ground.
this should come from the main panel.

Different areas of the country have different electrical codes. Some
rural areas have no electrical code (you said barn = rural?). Others
very old electrical codes. Most areas go by the latest NEC though.
So you would need to check with your local electrical inspector to see
if this was done to code for your area. I suppose it is possible that
a ground provided by metal conduit might be acceptable in some areas?
I would prefer a separate ground wire run from the panel myself - code
or not. I've seen a lot of conduit come undone!
Then in my area, electrical work on a rental can ONLY be done by a
licensed electrician. I don't know about your area. Check with your
local electrical inspector.
As to having an electrician do this work, the most DANGEROUS
electrical wiring I have seen done was do-it-yourself work on farms
and in barns. You would be wise to hire an electrician. If nothing
else, to just check the work which was done to be sure it is safe. And
if the work was done to local electrical codes and done properly, then
the landlord should have no problem with you hiring an electrician,
right?

Only one ground wire is needed in the conduit. Should be sized for
the lager circuit.
If box is metal, a pigtail is needed to ground it.
connect all grounds together. pintails from the box and each outlet
plus incoming wire and out going wire.
Use MC cable to run your 110V circuit. Romex only allowed in
residential inside finished walls. Or you could run EMT and pull THHN
wires. or even plastic conduit.
Second 220 outlet, run 3 wires BK/R/G ground gets connected to box
and outlet.
I always run a ground wire even if not required. Metal conduit just
cannot be trusted. Joints come loose or get corroded.
