Opinion

COLEMAN, Justice.

This is a suit for damages by reason of personal injuries sustained by appellant when an oil well perforating gun, which he was rigging up at a well site, exploded. Appellant was an employee of McCullough Tool Company. Oil Production Maintenance Co., Inc., also referred to as O. P. M., was the owner of the drilling rig. In answer to special issues the jury found that the sole proximate cause of the explosion was the negligent failure of the defendant to insulate a junction box, a part of the electrical system in use at the rig, in the manufacture and assembly thereof. The answers to all other issues submitted were consistent with a judgment for appellant. The jury found damage in a sum in excess of $500,000.00.

The trial court rendered a judgment for the appellee notwithstanding the verdict. Appellee’s motion alleged as grounds for such action that there was no evidence of probative force to justify the jury findings and that there were no facts introduced into evidence which would support any legal theory of recovery.

Appellant submits that the evidence fully supports the jury findings and that the facts found require the entry of a judgment in favor of the appellant. By cross-points appellee contends that the answers made by the jury are so contrary to the weight and preponderance of the evidence as to be clearly wrong and manifestly unjust.

In support of the judgment of the trial court appellee contends that there was no evidence that in the process of manufacturing and assembling the junction box installed at a position under the floor of Rig U-15 it negligently failed to insulate the box. A junction box, which was introduced into evidence, is a box 3" in width and 9" in length constructed of heavy aluminum open on two sides and with holes at both ends. The box is designed for plates of the same material to be attached to the open sides over water-tight gaskets by six screws. On each of the plates are two openings in which are fitted female electrical outlets, protected by metal covers attached to the plate by chains. When the covers are removed four appliances or extension cords can be plugged into the junction box. An insulated cable carrying two lines, one negative and the other positive, composed of many copper wires, enters the junction box at one of the holes in the end of the box. The two lines continue through the box and exit at the other end into a similar cable. Inside the box a smaller line is spliced into each of these lines to supply current to the outlets. The splice is soldered to secure stability and then is insulated with rubber or plastic tape over which is applied friction tape. The holes through which the cables enter and exit from the box are protected by hollow metal bolts and rubber gaskets. The cables are short and one terminates in a female plug, the other terminating in a male plug, both protected by heavy metal covers fitted with gaskets. These short cables are known as “pig-tails” and the length may vary on different junction boxes. Metal clamps attached to the box by screws are provided as a means of fastening the box to a rig member.

Within one or two days after the explosion in which appellant was injured, a witness, sent by appellant’s employer to investigate certain aspects of the electrical system, and who qualified as an electrical expert, by the use of a megohmmeter, found that a junction box located at position A, which was under the floor of Rig U-15, had an insulation resistance reading practically of zero and that another box had a reading of 800,000 ohms, indicating no re *841 sistance at Box A and less resistance than was proper at the other box. As a result of his tests he determined that no circuit other than the one going under the derrick floor showed low resistance. Other circuits went up the derrick and to the light near the end of the catwalk. He then removed a plate from the box at position A under the floor and found dampness and droplets of water inside the box. He also found that both the rubber tape and the friction tape were loosely and inexpertly applied around the splice. He testified that the tape should be applied tightly and that successive layers should overlap and bond •securely to the previous one and that this was not so applied. The tape would not stretch and there was no indication of deterioration, or that the box had in any manner been altered or that any work had been done on it. It was his opinion that the loose tape on the splice, in connection with the moisture in the box,* charged the derrick members with an electric potential of 115 volts, which would do no damage until the electrical path from Box A was completed back to the other conductor to the light plant source. He testified that Junction Box “A” was bolted to a rig member, and that it was energized because of the defective insulation and that all metal members of the rig connected with it would become conductors. However, he testified that a person touching any of the rig members would receive no electrical charge unless he completed a path to the other conductor. He gave his professional opinion that some or all of the members of the derrick were electrically charged from one side of the circuit, and that if the insulation in Junction Box “A” had been what it should have been, the derrick members would not have been electrically charged. He testified that when he made his investigation the derrick had been moved from the location at which the explosion had taken place, but that the derrick and its equipment were set up just as before.

Other testimony shows that the electrical system was specially designed by appellee for Rig U-15 and that while the junction boxes were usually placed at the same position each time the rig was moved to a new location, this was not invariably true. While it appears that the electrical system is removed from the rig when it is dismantled for moving, it does not appear that the junction boxes are disconnected from the electric cables. While the junction boxes appear to be interchangeable, differing only in the number of outlets and, possibly, length of pig-tails, there is no evidence that either on this particular occasion, or as a general rule, after the rig was moved the boxes were replaced in the system at random, or moved from one circuit to a different circuit. There was testimony that the junction boxes go back basically in the same places.

Another person employed by the McCullough Tool Company investigated the accident before the rig was moved. He also qualified as an electrical expert. He checked the truck and equipment used in connection with the perforating gun, and found that all safety precautions had been taken and that all safety devises were in place, and testified that the explosion could not have been caused by electrical energy from the power source in the truck. He found that the gun had been hooked up to the long electric cable carried in the truck and attached to a power source in the truck. This was a cable so designed and of such length as to be capable of lowering the gun to the bottom of the oil well. Several safety features were shown to be present which were designed to prevent the passage of electrical energy through the line from the power source prematurely. There is no evidence that the explosion was caused by electricity from this source.

The gun itself is about ten feet long and, at the time of the explosion, had been placed in the metal lubricator in which it is lowered into the well.
