What does Harmonised cable mean?
Harmonised Cable
Harmonised European standard cables, commonly known as HAR cables is an effort by CENELEC (a European standards committee) to harmonise the classification of cables that lead to a coding system that you will often see used to specify the detailed characteristics of a cable or flex.
What do cable codes mean?
Cable Designation
The HD 261 document, classifies the construction of the cable by allocating codes (letters or numbers) to represent the cable voltage, insulation material\, structural elements, sheath, special features and conductor type.
What depth should electric cables be buried UK?
All ducting must be laid with electrical cable warning tape, which should be installed at a depth of 240mm below gardens and paths, 100mm below roads and 650mm below agricultural land.
How do you bury a cable garden?
Bury in the Ground: Dig 24 inches
- At 24-in. …
- There’s one restriction: It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground.
- Burying the cable 24 inches requires more digging, so this method only makes sense if you have easy-to-dig soil or are renting a trench digger.
What does 6242Y mean?
Flat PVC Wiring Cable
Draka 6242Y is a flat PVC sheathed low voltage wiring cable typically used for small power and lighting applications. Individual cores are PVC insulated with two and three core options available, both include an additional un-insulated circuit protective conductor.
What types of cables are Recognised by cenelec?

What does G mean in cable?
G. = with green-yellow earth wire. Cable type key according to DIN VDE.
What does the letter O stand for on wire?
E – Elastomer – Usually hand in hand with the “T” for thermoplastic insulation. O – Oil resistant conductor insulation. O – Oil resistant Jacket. W – Water-resistant jacket (Not approved to be submersed in water)
How do you read a cable spec?
An electrical cable is classified by two numbers separated by a hyphen, such as 14-2. The first number denotes the conductor’s gauge; the second denotes the number of conductors inside the cable. For instance, 14-2 has two 14-gauge conductors: a hot and a neutral.
What is code for buried electrical wires?
Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
What cable do you use for garden lights?
Once outdoors, you should supply your lights via 1.5mm² three core steel-wire-armoured cable (SWA). Make sure that you only fit weatherproof lights that are suitable for outdoor use and that your circuit is RCD-protected.
Can you bury wire without conduit?
Direct Burial rated wire is approved to be run in the earth in accordance with the National Electric Code (NEC), usually without the use of conduit to surround it. The combination of the insulation material and its thickness keeps out moisture and other harsh factors to protect the wires inside.
Can Romex be buried?
Romex is a brand name for non-metallic paper bonded cable (NM-B, as printed on the jacket) with a PVC jacket. This is why type UF is suitable for burying and wet locations (or dry) where NM-B cable is suitable only for very specific dry locations.
What type of electrical wire can be buried in the ground?
Common types of cables with a copper conductor suitable for direct burial are USE-2, UF-B Underground Feeder Cable, and Tracer Wire. Aluminum URD Direct Burial Wire is the most commonly used direct burial aluminum wire.
Can direct burial cable be used indoors?
Types of Direct Burial Cables
Type UF cable is usually gray and comes in rolls that look like standard non-metallic (NM) sheathed cable. While standard NM cable is rated only for dry, interior applications, UF cable can be used outdoors as well as indoors.
Why is indoor wire more expensive than outdoor?
UF is more expensive because the insulation and sheathing is more complicated.
How far can you run electrical wire underground?
As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 percent voltage drop.
For 240-volt circuits:
| 14 AWG | 100 feet |
|---|---|
| 10 AWG | 128 feet |
| 8 AWG | 152 feet |
| 6 AWG | 188 feet |
Can I use UF B instead of NM B?
UF electrical wire is perfectly suitable for most NM-B applications, though it is unnecessary to use it because it is too expensive for indoor applications. When used as NM, UF-B has to comply with the standards found in NEC 2008 and NEC 2011 Article 334.
Can you use nm-b outside?
Answer: No, Type NM cable cannot be installed outside, regardless of the wiring method enclosing it.
Can you use UF cable above ground?
The use of UF cable on the exterior surface of buildings or structures is permitted by Sec. 225.10(18) and Sec. 334.10(3) of the NEC. If the cable is exposed to physical damage it must be protected in accordance with Sec.
