Question about Intermatic Malibu 300W Power Pack Transformer ML300RTW
I have a 300W transformer w 100' of 12 gauge wire. Runs fine with one 20w, one 11w and 3 50w floodlights. Connect another 50w flood and system runs between 1-3 hrs then shuts off w "E" error. Remove 4th flood and everything is ok again. ????? Ray
The following might apply to your situation, or not.
Malibu recommends matching wattage of bulbs to wattage of power pack.
In your case, you have 181 watts on 300 Watt power pack.
Based on other folks questions to fixya, this condition can burn out the power pack.
Has your power pack overheated and been damaged?
I don't know, but it might be a good suspect.
