When I first fitted it I hept an eye on it (don't have a thermometer) but just put my hand on it to see what it is like over long distances and it was normally only warm- mine is in the battery box with no airflow to assist any cooling but I don't think it needs any. Glyn ![]() ![]() |

Thanks Glyn.
Ours is mounted upside down in battery box. Suppose battery box wall acts as a giant heat sink. Upside down easier to get to terminals. Brendan |

If an electrical device such as a relay is getting hot (as in prelonged touch would hurt the finger) its a sign that something is wrong, i.e wrong size slected or drawing too much current due to a fault. The contacts will burn up, causing a high resistance to the point that the device would either melt or not work. A 200A relay should be warm / tepid but not hot, the coil will generate some heat, but not much. |
