I have a portable building about 50 ft away the house. I had an electrician come run a feeder to a subpanel in the shed. Looks like he tapped off of my Generac Transfer switch. When I opened up the subpanel in the shed I noticed there are 2 hots and a small bare ground coming in. Is there a reason why he did not run a Neutral? I only paid him to run the feeder and I was going to run the 2 circuits in the shed to the subpanel (2 shop lights and 4 outlets). Do I need to treat this subpanel as a Main? enter image description hereenter image description here

    Can you shoot some photos of the hookup on both ends? The notion of not running a neutral is alarming, especially if it's a proper electrician. – Harper - Reinstate Monica Dec 21 '19 at 2:50
  • I'll have to get some photos in the morning when I get home. – Karl Dicharry Dec 21 '19 at 3:02
  • Yes, can we have photos of both ends of this feeder please? – ThreePhaseEel Dec 21 '19 at 3:26
  • I'll take actual photos tomorrow, but the bottom photo is the same transfer switch I have. The eletrician ran the feeder wire off of the lugs that are under the red cover and the small bare ground to that bar towards to top left where it says neutral bonded. The top photo is the same box that is in the shed.. he has the 2 hot wires going to the terminals by the main breaker and the bare wire going to the bus bar towards the right.. – Karl Dicharry Dec 21 '19 at 4:02

    Since the 1999 NEC code update 4 wire feeders have been required. Without a neutral you would be limited to only 240v loads. And since it is a separate structure a ground rod is required. What size are the wires feeding the sub, and what size is the main breaker feeding transfer switch? Are the lugs bolt style? With crimped ends? – Ed Beal Dec 22 '19 at 14:29

Stop payment on the check

This guy is not a real electricion. This work is a hack job, with shortcuts all over the place that are insanely dangerous, and have never been legal, ever.

I guarantee you no permit was pulled, either. The inspector would not have signed off on this.

Subpanel connection pretends neutral=ground. Dangerous!

On the subpanel connection, the person is completely ignoring "Neutral is not ground" and doing something that was never legal, using the ground wire as neutral. It will kinda sorta "work", but if anything goes wrong with that ground wire, it will electrify every ground in the shed, and possibly, in the house. It's much worse than the old NEMA 10 killer.

No ground bars in the subpanel

Hello! Neutral and ground need to be separated in the subpanel. Ground bars are like $6, so this was a very cheap negligence.

I'll lay dollars to donuts there's no ground rod, either.

No disconnect in the shed

There's no main breaker in the shed - that's the usual way you install a disconnect switch for an outbuilding.

The panel is UNFUSED, WTH!!!!!

The feed cable to this subpanel has no fuses whatsoever. Nothing will keep this cable or subpanel from exploding into flame.

This is just not giving a damn. Negligence of staggering proportion.

The panel is double-tapped

Those lugs that the wires are hung onto -- are not made or rated for two wires. You can only put 1 wire per lug.

This is the bare minimum rigging to get it to barely work. I'd exepct this type of work in Kowloon City or Bangkok. Faked it and hoped you wouldn't notice. I would actually talk to the AHJ and warn that this clown is operating in your town.
