Our abc calbe conform to ASTM, IEC, SANS standards.……Including: abc cables, cvered line wire, service drop wire etc. Our Conductors conform to ASTM, IEC, BS, BS EN and DIN standards.…… Including: AAC conductor, AAAC conductor, ACSR conductor, ACAR conductor, AACSR conductor, etc.Īerial bundled cables (also aerial bundled conductors or simply ABC) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. Electrical power cables may be installed as permanent wiring within buildings, buried in the ground and run overhead or exposed.……Including: rubber cable, welding cable, URD cable, XLPE insulated power calbe etc.īare Overhead Conductors are used in overhead transmission and distribution network applications.They are also used for un-insulated hook ups, jumpers, grounding conductors and other applications. The assembly is used for transmission and distribution of electrical power. It is an assembly of one or more individually insulated electrical conductors, usually held together with an overall sheath. Power cables are mainly used for power transmission and distribution purpose. Simple, gets the job done, and no underground splices to worry about.Your email address will not be published.
#UNDERGROUND WIRE SPLICE INSTALL#
With suitable (and expensive) materials, you can keep the splice dry, but why make things hard on yourself.įor example, if you install a pair of new receptacles a couple of feet apart, then you can make all of the splices aboveground in the receptacle boxes. Water is the enemy, and underground means wet. While they are permitted with suitable materials, they are much more subject to corrosion and damage. IMHO you want a better solution than an underground splice. The splice will most certainly be exposed to water, and you will still need to use a splicing technique suitable for underground use and wet use. Such a box is quite 'open' often without a bottom in fact one technique is to dig deep and put gravel below the box to allow for better drainage. These are the 'Valve Boxes' that Arg suggested, and yes, they are used in just this fashion. Additionally, since there is no extra 'play' in the buried conductor, you will need some space to make the splice anyway.Īt I minimum, I suggest that you put this splice into a suitable underground access box, commonly called a 'Christy Box' (this is a trademark, but is often used as a generic name). If this is a GFCI circuit, then you will be more subject to tripping from minor 'leakage'. If (When) the splice fails, you will be stuck having to find it.
#UNDERGROUND WIRE SPLICE CODE#
It is merely 'safe enough' to pass the code writer's sniff test. Code is not a design manual, and bare minimum code is rarely a good design. Having said this, IMHO making this splice underground is a _bad_ idea. See, for example which can connect 4 #12 solid conductors, for direct bury, underground. Yes, this is a bit of code that is at odds with the generally required practise of putting all splices in junction boxes but thems the rules. You _must_ use splicing devices that are listed for underground use.
This is _explicit_ permission to make splices and taps in underground wiring without the use of a box. The water and minerals in the soil can corrode your wires as well as energize something close by.
The problem is that you can count on any underground splice becoming submerged or just damp on a regular basis. Although many situations are unlikely to kill someone, look up "stray voltage". GFCIs must be checked regularly and they do fail. If the circuit is GFCI-protected before the fault, it would most likely trip. you wouldnt make teh entire area above it electricified if your splice was bad - would you?" "Also, what is the danger of a bad splice underground. Check your state and local codes to ensure they are permitted in your area, get a permit and have your work inspected: Use something like this for your splices. I am not sure what the NEC has to say about this. Maybe someone more knowledgeable can comment on the possibility of putting your splice j-box inside a valve box with suitable drainage. That is, you will need a j-box at that 10-feet-short point, above ground. Yes, but plan to make the splices above ground.
#UNDERGROUND WIRE SPLICE FULL#
"But, this new wire wont reach the full distance, so I would need to splice in order to extend it another 10 feet or so.
