The neutral bar in the sub needs to be isolated and u probably need to purchase a separate ground bar kit. Now U need both an EGC, tying the main panel to the subpanel AND 2 grounding electrodes. With a bad neutral connection, a shock potential exists! This is because the neutral bar was bonded to the metal enclosure as well as any other metal that was bonded to the panel. The reason the allowance was removed is because if the neutral developed a bad connection, the neutral return current could find a different pathway.

NEC code prior to 2008 allowed a 3-wire feeder to a detached structure ONLY if there was no parallel metallic pathways. That is a common misconception that they are the same or serve the same function.

There is a bit to do with reduction of step potentials too from ground and now footings that we are standing on.Д«ecause a grounding electrode and an EGC/ground are 2 different animals. The rod is there for lightening strikes, we would rather have it diverted there vs carried via the wire back to the originating building or service if possible. If a guy has a grounded tool from the house and one from the garage come in contact, or a human is the link there is no potential difference between the 2. Some of the same issues as a fault, some probably flows over it but its short lived with a 4th wire, this wire ran WITH the service conductors delivers a fault directly to service main (others can explain more tech, impedance etc) but or also this wire keeps everything metal on this service connected to it at the same potential. If you used a block-style splice, make sure the silicone is covering. You should see this all the way around the wire on both sides of the splice. Verify that the sealer is coming out around the wire. Use a heat source to shrink the tubing down to the proper size. Unbonding at the second building allows for the neutrals to be insulated keeping all current on insulated wiring. Slide the heat-shrink tubing over the splice. For example, grounded furnaces in both buildings connected by copper lines, some of the current will flow on this tubing between buildings. With a bonded N some of the operating currents flow on any metal.

The problem really came with the advent of so many more metal interconnections between buildings, gas. 3M Cold Shrink QS-III Concentric Neutral Single Conductor Cable Splice Kit. The earth will not return a fault to trip a breaker, only a wire does this. We offer a variety of medium voltage splice kits to splice or join together. Its difficult to get past the fact that the ground rod basically does nothing here for the sake of this part of the conversation but there must be a wire pathway with the power conductors back to the main it came from. This used to be acceptable but was changed in 96 maybe? But anyway the old allowed 3 wire with neutral bonded to the ground at the second panel but this created a lot of problems with alternate pathways for neutral currents. This is really a service to a detached structure from an existing service. Select the method that's right for you when ordering.Subpanel is a slang term.
