Just checked and it does have a ground connection.
The neutral and ground are only bonded in a sub-panel of an out building if the code requires a buried ground rod or plate at this location.
By National Electric Code only the Main Panel should bond ground and neutral. If subpanels have ground and neutral bonded, it could cause ground loops and shock hazards.
You'll have to explain your problem better.If HOT black and Neutral White in your house wiring are both hot then Neutral is NOT bounded to ground in main panel and neutral could be floating. There should be no voltage between Neutral and Ground (Bare wire in panel). By code if there are multiple panels Ground is only bonded to Neutral in th emain entry panel. I have seen cases where this bonding was not done. At your main panel check voltage between neutral and ground. It should be zero.
First off, this is for a single phase 120/240V system only. The ground and neutral can be bonded at the receptacle but not instead of bonding them at the panel.You should always have them bonded together at the panel in a single phase 120/240V system. Otherwise you risk having a floating neutral in your system.
If you are working with a sub panel, there are a few reasons to isolate the neutral. Firstly, currents will then return to the main panel and service ground.

The main electric panel is where neutral is bonded to ground. There is usually a screw or strap that connects the two so the same type panel could be used as a subpanel and have the neutral and ground unbonded in subpanel.
A neutral grounding resistor panel is used to resist fault current to the ground. It is used for alternator protection protection purposes. When a fault occurs in the alternator, the panel helps force the current to the ground.
Ground wire to neutral wire.
In North American residential homes, there are 3 wires coming from the utility company, two "hots" and neutral. The two "hot" conductors get connected to the main breaker. The neutral gets connected to the neutral bus bars located along the sides of the breaker box. There is a set screw that is placed in the neutral bar that screws into the distribution panel enclosure thereby bringing the potential of the neutral bars down to zero. The wire from your ground rod is also connected to the neutral bus bar, and thereby it is connected to the neutral from the power company. This is also often bonded to the copper cold water plumbing in the house if the home is not plumbed in PVC water pipe. White circuit wires are then connected to the neutral bus bars. Also in the distribution panel are ground bus bars. The ground wires from circuit cables are connected to these grounding bars. Do not under any circumstance terminate the white and bare ground wires together. Ground wires to the ground bar and white wires to the neutral bar.
In any distribution panel there are individual bars for each termination. The ground buss is in direct contact with the metal enclosure. The neutral is isolated from the metal enclosure. The only place where the two come into contact with each other is where a bonding screw protrudes through the neutral bar and into the metal enclosure.
Neutral is grounded in a distribution panel. At best, it is only a few tens of millivolts away from ground and it certainly would not be DC - it would be AC.
Take a look at the junction where the ground wire and the neutral enter the panel. There you should see a green grounding screw that protruded through the neutral block and into the metal enclosure of the distribution panel.
