I have  5 low voltage lights (20 W )bulbs in each with an individual transformer (12 V0 each plugged into a duplex outlet connected to the switch. In the past 3 months I have "blown 5 " individual transformers., Any suggestions or ideas as to what the problem might be?

Thanks

Check the specs on the transformers, it's probably your output wire size.

Sometimes its better to use 1 trannie with a
higher watt output than seperates its cheaper too.

You might want to check to see if the voltage rating of the bulbs matches the rating of the transformer, if you are running if you have mismatched either the bulb or transformers, you can have these kinds of problems. In other words, if you have a 12v transformer, use 12 volt bulbs.

Good luck

You state that you are using low voltage lights, you then say that they are 20 Watts each, The wattage consumption of the bulbs in no way dictates that they are low voltage. A 20 watt bulb could just as easely
be opperated on a 277 volt system as it could be on a 12 volt system. Read the bulb to determine the voltage that the bulb operates at. make sure the output voltage of the transformer is the same. The output wattage of the transformer should be rated at 1.25 times of the total watt draw of all items connected to the transformer. This princable only applies to straight resistence and not to moter loads
