600V Power Armoured Cable Construction at USA

Consult the applicable specifications. Do you know what they are? Maybe yes, maybe no. I doubt it.

Form your own opinion after doing some basic research, or getting the proper education and/or experience.

We cannot inject you with knowledge.

Ask a cable supplier for help. Pray.

Do your own work, or find a job you can do without asking strangers to do it for you.

We are doing project at India wherein client is from US. In our normal standard, we used to propose 3C or 4C , Copper or aluminium,xlpe insulated, Galvanised steel wire round armoured or flat stip armor, PVC insulated cable for Underground and above ground (over tray) application.

Where as client is insisting as per US regulations but they have not shared the specification requirement.

That is the reason I asked above question.

pls clarify.

So then now its time to step it up an acquire the specifications and code.

Your client should at least have the courtesy to let you know which one it is.

You deserve each other.

CR4 is not the end Client. Ask the end Client or a technical representative working for the Client instead.

US will use IEC and IEEE standards so you client needs to stipulate the standards he wants to use. Simply ask him for his standards.

There's more to your question than you realize, and you didn't even ask about wiring where jet fuel abounds. NEC Section 513 Aircraft Hangars is your guide to how it's done professionally in the US. You can purchase it online from NFPA.org.

It appears that this for for a US customer at a site in India - therefore applicable codes of India apply foremost.

Submit the design based on Indian code requirements and tell the customer that these are to our codes as required for construction here. If they want something else they will tell you, if they even know what the US codes are. If legal for use in India, then modify your design to meet.

If however, this is a small piece of a hangar installation for use in the USA, you have a lot of "homework" to do.

The thing about US codes is that they vary by region. The NEC is the most common, but only applies if the local building code says it does. It has no power on it's own, only the power invested by laws which are part of the local entity, usually state, but many times local municipalities and counties. These can choose to use the NEC in the intirety or use the NEC with various exceptions or provisions. In some parts of the country other codes are followed, and I will not enumerate them all. My employer, before I retired had operations in every state and sometimes it was very confusing. Add to the confusion that sometimes inspectors did not know the code that was applicable and made up their own rules.

I would intend to follow your local building code because you have to, to be able to do construction in your area. I would also purchase a copy of the most recent NEC code on the internet with express shipping and study it carefully. If anything in that code exceeded the local code, but did not violate it, then I would inform the customer of the difference in cost, and let him make the decision. If the local code exceeded the NEC in quality, the customer should not have a problem but stilll should be informed. I would be quick to inform the customer ahead of time, before starting the project that this would be the way I was going to proceed. See what his reaction is.

I would like to have only answer from your side that whether (1) armour cable (600 V) will have steel wired round armor or strip wire armour or continuous and interlocking spiral wrap

(2) type of conductor aluminium or copper for 600 V application

You can have steel wire armoured or an unarmoured cable. Steel tape armour is found on PILC cable. You have a PVC 600-1000V cable. Are you using the steel armour for earthing and circulating earth faults?

The conductor can be either Al or Cu. The Al will be larger than the Cu. They will both operate in the voltage range of 600 Volts.

If it was my choice I prefer Cu with XLPE insulation and steel wire armour, a CCG or Pratley gland and it would be a 4 core cable. Use a cable standard and manufacturer data sheet to select your cable. You know your system I would imagine. Why do you want to connect an Al cable to copper busbars? More cost and more hassles.
