Wire caps, aluminum #8, and junction boxes

[dietcoke]

Hello,

I am hoping you folks can help me with a stupid question.

I paid my builder to put in a 220v run for an outdoor hot tub. The hot tub in question runs at 50A.

The builder appears to have used several pieces of #8 aluminum wire. At 2 different points along the run, the wire goes into a junction box where it connects with the next piece via what looks to be a standard wire cap. I would assume whoever did the work did not have a long enough piece of wire to do the entire run.

I have heard that because aluminum expands at times, it is generally not advisable to use wire caps. If anyone could shed some light on the validity of that statement I would greatly appreciate it. Does this sound kosher for code purposes?

Thanks!

Sorry guy but this site is not for home owners or DIY`S.The questions you are asking are DIY questions.No offense but I am sure the moderators of this site will,lock your thread out.The best advice I can give is to call a licensed electrical contractor in your area and present them with your concerns......

While I agree with the no-DIY-questions rule, this is serious enough to tell you:

Even without the unnecessary splices (which definitely are an issue), the #8 aluminum is way undersized. Even copper should be #6 for this load.

Your builder has done a dangerous and illegal installation.
