Best Software To Calculate Cable Ampacity?

British Standard 7671 is undoubtedly the best software, according to the hundreds of postings elsewhere in this forum..

Check with Mr. Google.

I just use a VOM.

Also see previous discussions on CR4 to this commonly asked question.

OP requested "Best Software To Calculate Cable Ampacity? "

ronclark quote "I just use a VOM."

Ron how do you do that?

By the way, I hope you beat BAMA.

Find the area with the most heat, rate for that area, done.

" working as a head of engineering " ?? this is an amazing question for " a head of engineering " to ask. unless the " head of engineering " also has a SINK.

A simple wire guage table will give you the current capacities of the wire.

You will neeed to know the wire size ( guage ).

Longtooth, what you posted do not exactly apply in this case. The OP has specified some environmental conditions that would alter that ampacity tables.

Perhaps the whole thing should have been off-topic; it was intended as a starting point; he does not specify anything other than vague implications. I guess ( ! ) a vague reply did not convey the sarcasm correctly. OP, after all is "a Head of Engineering". I guess ( ! ) one may be a head of engineering without actually knowing anything about the engineering. Try to get that job here.

I stand by the answer; From WIKI : "Ampacity is defined as the maximum amount of electrical current a conductor or device can carry before sustaining immediate or progressive deterioration."

Nothing was said about whether the wiring is already installed or not. Is it direct bury or is it in conduit ? Is he wanting to know how much he can add to an existing load, or designing to max from the start ? What safety factor does he want / require ? What's the local code ? Redneck said it best.

Hello Longinthe tooth,

Thanks for your reply.

I must have put the question with more details. However, i have already googled before ask this question in the forum and i found that there are lot of softwares and each follow different standards. Some only follows IEC and some follows IEEE / NEC. We are usually dealing with EHV cable installations and most of the time we encounters install the cables in an unfavorable conditions, i.e, laying cables underground with many heat sources crossing each other which derates the Ampacity of Power cable. Most of the time we do the ampacity calculations manually and some times due to of above conditions we depends on the manufacturers who have the softwares that only can do the calculations for above conditions. And yes, we had a thought of buying one (Software)...

Though having some basic knowledge on the softwares for Cable Ampacity calculations, i put this question on the forum just to exchange some ideas with the people like you may know more on the same....

The latest version of CYMCAP should serve your purpose.
