I Have An Eexe Electric Motor Which Is Labelled As T3, I Understand This To Mean That The Temperature Reached By Any Part Of The Motor Will Not Be Any Greater Than 200°c. Is This The Case And Do I Need To Consider Ambient Temperature Effects? |

Answer» This is true and if there is no ambient temperature range marked on the equipment then the T rating is BASED on a range of -20°C to +40°C. Any other range must be marked on the label. Q. A flameproof EExd enclosure has a 32mm ENTRY and we need to use it for a 20mm cable gland, is it permissible to use TWO REDUCERS to achieve this? A. No, EN 60079-1, the standard for flameproof equipment states that for any entry only one reducer can be used, also that reducers or adapters cannot be used at all with stopping plugs.
