I want to replace the sockets in the kitchen and have found that on every existing socket the wiring has been stretched to its limit to reach the connectors! (Not Guilty!!!) Now, obviously, I cannot connect to the new sockets as every wire is about an inch short leaving no working space to be able to connect and tighten the screws. Is there a safe way to extend the wiring by a couple of inches or so to be able to reach the sockets. In this particular instance it is not practicable to relocate the socket further back along the run of wiring to free some up as the wiring goes left and right away from the socket. It appears to me that the sockets were installed when the new kitchen was installed some10 years ago and then the wiring pulled thru to the next socket etc. leaving absolutely no slack. Thanks
