[QUOTE="SPECIAL LOCATION, post: 473926, member: 250"] For short term use standard flex is perfectly ok outdoors, e.g. have a look at what is on an electric lawn mower.... Or caravan electric hooks-ups use flexible cable for short term connections, e.g. maybe couple or three weeks in one go... BUT.. UV light will deteriorate the PVC on cables (and loads of other plastic items as well, our watering can has perished being left out doors all the time!) Also extreme of cold or heat, and mechanical damage from garden tools or wildlife having a chew etc... will all damage the cable. So any permanent electrical connection needs either additional mechanical protection by use of more appropriate cables such as SWA or using conduit to enclose the wiring... Personally I would suggest you get an electrician round to have a look at you requirements and give you an estimate.. as from you comment about using an RCD plug with RCD on all your breakers at the consumer unit suggests you don't fully grasp the purpose or how some protective devices actually work.. Stating a budget price of £2 per meter may not be an electrically safe option, I would strongly recommend you look for safety over price.... If you do get it wrong electricity will kill a healthy adult in less than half a second... and outdoor wiring is always a more dangerous environment than internal electrical work. Guinness [/QUOTE]
