Hijack topic a bit. Won't it cause heating?
My switch for heaters have a bit too much wires inside the box. So I lazy cut and just stuff everything in. What I notice is it heats up from time to time. Major problem? It won't heat if switched off right. |

QUOTE(ozak @ Nov 29 2016, 02:31 PM) Your heater wire carried higher Ampere compare light. Thanks dude, not so good at electrical.That cause the wire heat up. Cut short the wire to reduce it. But it still heat up. Unless you change the wire to bigger gauge.  So what you mean is, even if I cut it short it'll still be hot. Except now is hotter because I stuff it all inside the box? Any risk of fire? I can feel the switch is warm to touch, but not hot. |

QUOTE(ozak @ Nov 29 2016, 03:23 PM) It is not much different because the wire is really not that long. Cut it short is to make it more proper and have some space for the hot air out. (not much also) I'm using a 20A switch. Probably the wiring then. Find wiring work to be a hassle, especially with switch fittings since it can be hard to get them flush if the box size differ from the switch plate you're using.You won't get risk of fire if 1) the time using is short. 2) The heater KW doesn't exit the max wire ampere carry. Maybe around 20A. or 4.8kw. 3) the connection not loose and tight secure. switch and heater side. Get a better higher Amp switch. |
