Why did my Christmas lights go out?

Hi everyone!

I strung about seven 25' strings of C9 Christmas lights together and when I got to the last one, they all went out. Turns out the fuse inside the plug on the first set blew. I replaced the fuse and it worked for a minute but once again, the fuse blew. What could be causing plug fuse to blow?

Too many strings in a row. Most sets are limited to three connected end-to-end. It should say on the box.

Plug no more than three of these strings together. No more than six (150 7W lamps) on a standard 16-AWG cord or 12 on a 12AWG 20A cord.

yep.....as stated.....too many lights.

The bulbs are 7 watts each.....25 bulbs = 175 watts per string.

"I strung about 7 strings" translates to about 1225 watts.....a little more than 10 amps.

This is likely more than the rating of the fuse and exceeds the capacity of the wire.

I don't have the box anymore but I sort of thought that might be the problem. I have now put 3 strings on one and 4 on another (had to go get another long outdoor cord; guy at Ace said 4 on one would be ok). All straightened out now and my yard is all merry and bright!
Thanks everyone and Merry Christmas to all!!
