Here we used a special to Israel three square pin plug rated at 16 amps (230v). When we moved into this apartment 12 years ago EVERY outlet was burnt. The plugs are rated at 16 amps PEAK, not continous duty. So they work fine for a tea kettle, etc, but they will burn out with a heater, dryer, washing machine (if it heats water), and so on. Israel has now moved to an equivalent three round pin plug, which I assume is just as bad. I replaced all of the high current items that are used for any length of time, with 25 amp continuous duty "air conditioner" plugs, even if they only draw 16 amp or less. Geoff. -- Geoffrey S.

(these are the usual hardware store orange outdoor extension cords with the molded in plugs and sockets.) evidently the sockets at least on the batch i got just don't make good contact with the plug. i should do an autopsy. |

:What causes heating of electric sockets as well as melting of plugs on :the live connection The real answer is "excessive volt drop at the plug/socket interface". This could be due to excessive current being drawn or high resistance at the connection interface points. |
