Evasive problem found and solved.

Had one of those 'it only works when the serviceman is here' problems. Fortunately Micheal was able to find the problem and find an effective less costly alternative to the obvious solution of running new conduit. Very satisfied with Haas & Sons overall customer service and Micheal's creative solution that saved us money. Haas & Sons will be our 'go to' electricians for any future needs.

I removed a damaged 2 gang box for switches then replaced it with a 2 gang weather proof box and a in use bubble cover and replaced the dimmers. Then I came out of the top of that box and ran 1/2 inch seal tight up the post and over the top of the deck to a weather proof box I installed and installed a weather resistant receptacle Then from the bottom of the 2 gang box I came out of that and installed a weather resistant gfci and a weather proof box. This gfci controls the receptacle for the tv This has a 1 year warranty

Installed a new circuit for garbage disposal that will be installed at a later date. Ran wire from sub panel in basement through drop ceiling and into sink cabinet. Circuit is protected by a AFCI breaker and has GFCI installed for the receptacle. There is a switch in the cabinet that will power the gfci on and off. Verified proper operation of all completed work with customer.

Run 50 amp circuit in garage for plug in car charger I installed a 50 amp car charger plug. I installed the 1900 box then ran 1 inch pvc up the wall in the garage over the garage doors then converted it over to seal tight. I went in the wall down to the panel. Then I ran my wire through the pipe. I landed my wires on a new 50 amp two pole GFCI breaker. Then installed the outlet. I tested the outlet and the breaker. It’s putting out 240 volts I then spackled any holes created over the panel Customer did not want a surge protector at this time and also didn’t not want us to service the electrical panel. The work I preformed is protected by a 1 year warranty

Completed interlock kit on main breaker panel. This kit allows back up portable generator to back feed home safely. This makes it so that the generator breaker can not be on at the same time as the main breaker. This protects the home and people working on power lines to restore power.
