Mike Lamb Posted October 7, 2015 Report Share Posted October 7, 2015 In my opinion, this electrical feed to the AC compressor is subject to damage. Would NEC 334?30 be the applicable reference for this? Since the compressor should have a space between it and the house, what is a practical solution to correct this?

kurt Posted October 7, 2015 Report Share Posted October 7, 2015 Secure the loop back to the house so it can't be snagged. Quote Link to comment Share on other sites More sharing options...
Jim Port Posted October 7, 2015 Report Share Posted October 7, 2015 Article 334 is for NM cable and does not apply. Article 356 or 350 applies. Within 12" of the box and no more than 3' between . Quote Link to comment Share on other sites More sharing options...

Most new construction mounts the compressor on steel brackets. It definitely keeps the unit above grade. Quote Link to comment Share on other sites More sharing options...
Erby Posted October 8, 2015 Report Share Posted October 8, 2015 Wish more of them around here would levitate the units like that. Quote Link to comment Share on other sites More sharing options...

plummen Posted October 9, 2015 Report Share Posted October 9, 2015 The lazy installer should have shortened up the whip and strapped it to the house or lineset to support it.[:-yuck] Quote Link to comment Share on other sites More sharing options...
edwardh1 Posted November 10, 2015 Report Share Posted November 10, 2015 does that levitation transmit a lot of noise into the house? Quote Link to comment Share on other sites More sharing options...
Jerry Simon Posted November 10, 2015 Report Share Posted November 10, 2015 does that levitation transmit a lot of noise into the house? If the brackets are secured to a poured concrete foundation, zero noise. Quote Link to comment Share on other sites More sharing options...
ejager Posted November 16, 2015 Report Share Posted November 16, 2015 Its really nice to see them supported like that. Cuts down on damage from the weed whipper and little 'Fluffy'. Occasionally still some damage from Great Danes... Quote Link to comment Share on other sites More sharing options...
Inspectorjoe Posted November 17, 2015 Report Share Posted November 17, 2015 The biggest benefit of the foundation-supported brackets is that the unit won't tilt out of level if the backfill settles. Click to Enlarge 64.96 KB Quote Link to comment Share on other sites More sharing options...
John Dirks Jr Posted November 17, 2015 Report Share Posted November 17, 2015 I find problems related to the brackets sometimes. I've found the bracket arms set too wide and the AC unit is barely hanging on the ledges. A bit of vibration from normal operation and the unit will walk to one side then slip off the other ledge and fall in. I've also found grading issues around them. Sometimes the bracket is installed before the final grade is finished. If the bracket is low then dirt gets piled around it. They almost never fill the inside area and the result is a hole that catches surface water against the foundation. Quote Link to comment Share on other sites More sharing options...
rjbrown2 Posted November 17, 2015 Report Share Posted November 17, 2015 My machine design 'perfesser' would not like that stress concentration point at the 90 degree bend. I would feel more comfortable with gusset plates welded on. That unit is going to be vibrating on the end of those cantilever beams for years and years. Oh, I'm sure they will be well tended, the rust wire brushed off, and painted regularly Quote Link to comment Share on other sites More sharing options...
kurt Posted November 17, 2015 Report Share Posted November 17, 2015 Look closely...there's a reinforcing strut in there. I usually see them with struts. Brackets work great. If something is vibrating off it's mounts, something was done wrong. Quote Link to comment Share on other sites More sharing options...
