Butted Splices: Western Union splice for small gauge solid conductors. Multi-conductor cables should utilize staggered splices to decrease the bulk of the jointed area. Rat tail joints are can also be used for solid conductor cables, and are most commonly seen with electrical branch wiring. A naked joint is not very strong. Wire nuts are used as protective covers for these joints, and also provide a mechanical connection for added strength. A fixture joint is also commonly seen in electrical branch wiring where wires of different diameters must be joined together. Split bolt splices are simple mechanical joints normally reserved for residential and commercial grounding conductors, but can be seen in some larger commercial industrial locations or a residential service entrance.
Running Splices: A Knotted tap joint is used to connect a branch wire to a continuous wire.
I thought so. A buyers home inspecter says the splices,connections must be in a box "as per code".
Totally important!The connections must be well made and the wires tightly joined to prevent a loss of voltage to the device powered. In high current situations a poor connection causes heat at the connection and oxididaion of the wires and no more or intermittent connections.Most problems in electrical is not a short but: an open connection.Additional AnswerIn the case of high-voltage underground cables, the restoration of the insulation is critically important, as is restoring the cable's waterproof integrity. The skills required are such that cable jointers serve a full apprenticeship in that particular trade.
Answer for USA, Canada and countries running a 60 Hz supply service.Assuming the splices were made correctly, meaning tight, and assuming the wire nuts did not otherwise fail, there is more heat than the wire nuts were designed to withstand. Such splices in a transformer should be limited and eliminated if at all possible. Such splices in a transformer should not be made in close proximity to the coils. If there is not space or a compartment to isolate the splices from the heat, you need to install a different method of splicing that can withstand the heat.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
If all your joints were ball and socket joints, you would find movement and stable posture difficult. Joints have the structures they do to facilitate many functions, including stability, protection, and movement.
No, not all joints can bend. Joints such as the fixed joints in the skull, called sutures, do not allow for movement. They are specifically designed to provide stability and protect the brain.
all of them...
without joints, you can't type, run, and all sorts
No, not all joints allow movement. There are three types of joints: synarthrosis (immovable), amphiarthrosis (slightly movable), and diarthrosis (freely movable). Synarthrosis joints, such as those in the skull, are immovable.
we need joints to keep our body up right with no joints our bones will be all over the place and floppy.
Movement is not possible incase of fixed joints
If joints are popping all day long no matter what motion is attempted, this could mean a loss of cartilage around the joints. A doctor should be consulted to help ascertain the nature of the ailment.
Ball and socket joints, such as the hips and shoulder joints, can move in all directions.
