My mining shack is sending it's warm air to my basement to heat up the house, and since a few days I noticed a burned ordor coming from the vent.
Found the issue this morning 





With the current plastic I dont think it would have started a full blown fire but I guess i'm out to the DIY shop to buy some electrical parts
The multitap is rated for 3500w and was getting 2600w so maybe it was just some bad contact
