This is only my second post and I pray it is deemed on topic. This forum has given me a lot of insight however a forum search left me without answer here.
Most likely because you are all WELL above my knowledge level.
I'll try to make this short and again pray I'm on topic.. I live in florida and inherited a mess... I don't have much cash and only general electric knowledge. My inheritance property also inherited a code violation... And pretty imminent fines. Since the breaker was not within sight of the hot water heater I must install a disconnect. I do have a certified state electrician who will pull the permit but that is on the requisite that I do the labor on my own and he simply does safety and compliance inspection!
( Journeyman opportunity?) :)
I sent a picture to him and he said the conduit may not be the "right kind"
My opinion on the dry use only was just that... Indoor use dry locations.
Yes I hate that the conduit is exposed but again this is an unfortunate inheritance that I just want to comply until I can afford a professional.
I have researched that it must be supported no more than every " memory"
48 inches...
Where I pass through the wall and exterior have exterior rated box and conduit...
Interior box is also exterior rated passing through wall.
I read that a span of 6 feet or more from a fixture must have an independent ground source?
The wire is 10 gauge 3. AWGI guess my question is this..
1. is this considered independently grounded?
2. Is what you see so far (although ugly)
Safe and in compliance with NEC?
Additional general info:
The span of this conduit is 8 feet interior.
The pre existing wiring was open cable wired to a 40 amp 220v ( power is off but since it's a double breaker I assume 220)
I do not expect however welcome direct answers... If not can I please be pointed in the direction to learn on my own the answers to the issue I have.
I pray my second post is in the appropriate forum and of the appropriate nature. Just remember even you guys once we're 22 year olds with no knowledge of electricity other than God's gift of common Sense. I'm trying so hard.
This is also my first attempt at showing photos on here so I pray that as well is to par.
Thank you all.. I envy your talents. Call this a kind deed?
Advice suggestions criticism...
( Power has been off for over a year but I did check everything with a voltmeter before touching.)
Also load side is not installed because if I'm on the wrong path I can not afford more mistakes :(
What you see is from the hot water heater to disconnect. What is missing is disconnect to box... Through wall to exterior rated conduit to breaker panel...
And it's missing a dead face so God bless her memory but she must have had faith in me.

The exception only applies for connections within an accessible ceiling to a luminaires or other equipment.
Code Change Summary: Code language was added to address the use of flexible metal conduit fittings as a means of support.
Most of the time, lay in luminaires installed into a suspended grid ceiling are wired to a junction box above ceiling with the factory made 18 AWG fixture whips that come with the luminaire. Sometimes, MC or AC cable is used instead. Once in a great while an electrician might use flexible metal conduit (FMC).
The general rule for securing and supporting FMC is to fasten it within 12 inches of the box and secure it no further than every 4.5 feet. If the FMC is installed above an accessible ceiling, exception 4 allows the support spacing to be increased to 6 feet &#;from the last point where the raceway is securely fastened&#;. The question has been, what is considered &#;the last point where the raceway is securely fastened&#;?
In the NEC®, that question has been answered by a code change to exception 4. According to the new code language, for the purposes of this exception, listed flexible metal conduit fittings shall be permitted as a means of support. This means that a 6-foot length of FMC installed with listed fittings above an accessible ceiling between a junction box and a luminaire &#;or other equipment&#; can go without any additional strapping or supporting at all.
The new code language aligns with similar existing code language for MC and AC cables. A similar change occurred for liquidtight flexible metal conduit (LFMC) at 350.30(A), Ex. No. and for liquidtight flexible nonmetallic conduit (LFNC) at 356.30(4).
Below is a preview of the NEC®. See the actual NEC® text at NFPA.ORG for the complete code section. Once there, click on the &#;free access&#; tab and select the applicable year of NFPA 70 (National Electrical code).
