Type RHH/RHW

[Twoskinsoneman]

Was reading some old threads about weldind cable vs Type W vs Type RHH.

Does Type RHH have the flexibility that welding cable has.
I have a couple of places where using THHN 250 MCM is a real pain. If I could use welding cable I would do it in a heart beat. How ever it's not allowed...

Would RHH get me that same flexible type conductor?

Thanks

No. The insulation type does not change the physics of the conductor...

IS there a more (very) flexible alternative to THHN in these bigger sizes?
I certainly get a workout trying to bend the stuff.

Invest in a good set of cable benders.

Nope all it means is the insulation is rubber rather than plastic. Now with that said you can get RHH'/RHW with class H, M, and I stranding aka extra flex and super flex.

Here is one welding cable with an RHH/RHW listing.
