NMD90 cables may be used for both exposed work in dry locations or concealed work in dry or damp locations. The maximum allowable conductor temperature is 90°C. The minimum recommended installation temperature is -25°C for two-conductor cables and -10°C for three-conductor cables (with suitable handling procedures). Material should be properly stored above 0°C for 24 hours prior to installation. The maximum voltage rating for all intended applications is 300 volts.

Q:What are intrinsically safe cables?
A:Intrinsic safety is a protection technique for the safe operation of electrical and electronic equipment in hazardous areas where any ignition source needs to be eliminated.
Electrical cables are essentially sealed and so may be regarded as intrinsically safe in certain applications if protected from damage, external electrical or magnetic fields (EMI), and isolated from non-intrinsically safe circuits. The junctions and switches pose a potential hazardous ignition point in these environments and circuits. Intrinsically safe cables are usually coloured blue so as to identify the potential risk of the electric circuit and the need for special consideration. The cables are often protected by tough sheathing materials such as polyurethane to prevent any mechanical damage which could compromise electrical safety. Examples of intrinsically safe cables include the French Standard NF M87-202 instrumentation cables.
6.What are cable ratings?
Cable ratings determine the parameters within which a cable can be safely used. The most typical cable ratings are temperature, voltage and current.
Temperature rating is usually defined as one of the following:
- Max conductor temperature rating
- Minimum installation temperature rating
- Minimum flexible temperature rating.
Voltage is usually defined in terms of the following:
Uo = The R.M.S value between any insulated conductor and the earth or metal covering.
U = The R.M.S value between any phase conductor and another phase conductor or system of single insulated conductors.
(Um) = Maximum system voltage
The current rating is usually defined in terms of:
- Normal maximum continuous current rating
- Short circuit current rating
Cables may also be de-rated depending on the method of installation, for example, a cable installed in a thermally insulated wall will have a lower current rating than a cable of the same size and type which is installed in free air or in an open cable tray.
Cables installed in the ground at a higher than normal ambient temperature will have a lower current rating.
