Definition of: Dado.

In building; dados are panels fixed to the lower half of internal walls.

Definition of: Dado rail.

In building; dado rails are decorative and/or functional rails, usually made from moulded timber, fitted traditionally to internal walls to protect them from damage by chairs.

Definition of: Damp-proof course.

In building; a damp-proof course is a waterproof membrane installed in walls and floors to pre- vent moisture causing damage by rising upwards through the structure. Also termed 'damp course' or 'DPC'.

Definition of: Design Current.

In electrics; design current (of a circuit) refers to the magnitude (rms value for a.c.) to be carried by the circuit in normal circumstances.

Definition of: Direct Current (DC)

In electrics; direct current (DC) is a type of electricity transmission and distribution by which electricity flows in one direction through the conductor, usually relatively low voltage and high current. To be used for typical 120 volt or 230 volt household appliances, DC must be converted to alternating current, its opposite.

Definition of: Disconnector.

In electrics; a disconnector is a mechanical device which, in the open position, complies with the requirements specified for the isolating function. Another term for an isolator.

Definition of: Distribution board

In electrics; a distribution board is an assembly containing switching or protective devices (e.g. fuses, circuit breakers, residual current devices) associated with one or more outgoing circuits fed from one or more incoming circuits, together with terminals for the neutral and circuit protective conductors. It may also include signalling and other control devices. Means of isolation may be included in the board or may be provided seperately.

Definition of: Distribution Circuit

In electrics; a distribution circuit is a circuit supplying a distribution board or switchgear. A distribution circuit may also connect the origin of an installation to an outlying building or seperate installation, when it is sometimes called a sub-main.

Definition of: Distributor

In electrics; a distributor is a person or company who delivers electricity to consumers using electrical lines and equipment that he/she owns or operates.

Definition of: Dopant

In solar PV manufacturing; dopant is a chemical element (impurity) added in small amounts to an otherwise pure semiconductor material to modify the electrical properties of the material. An n-dopant introduces more electrons. A p-dopant creates electron vacancies (holes).

Definition of: Dormer window.

In building; a dormer window is a window that protrudes from a pitched roof allowing the glass to be held in a vertical position.

Definition of: Double Insulation

In electrics; double insulation comprises of both basis and supplementary insulation.

Definition of: Dry joint.

In building; a dry joint is a brick or timber joint that is not bonded with mortar or adhesive.

Definition of: Dry lined.

In building; dry lined is an internal partition or cladding constructed usually with a timber frame and plasterboard.

Definition of: Dry Rot.

In building; dry rot is caused by a fungus and occurs when an open, potentially damp area is insufficiently ventilated.

Definition of: Ducting.

In electrics; ducting is a system of shafts or tubes designed to carry and protect cables or pipes.

Definition of: Dwarf wall.

In building; a dwarf wall is a low wall, for example one constructed to support joists under the ground floor.
