I have a cigarette lighter plug and socket rigged up in the house for a
special purpose being drive by a 5VDC, 10 amp supply. The circuit after
the plug is drawing about 7.5 amps. However, upon removing the plug, I
find that it's quite warm almost too hot to touch towards the tip.
Nowhere else throughout the wiring is anything that warm. I am using 14
ga wire throughout and the plug also used 14 ga wires. Is this amount
of heat normal for the plug or is something causing it? Thanks.
