Mobile Transformer GEC?

[PowerdT]

If the transformer is isolated, do you need to bond GEC connection?

If the transformer is mobile, do you need to bond GEC?

I can’t find in NEC regarding mobile transformer

What is a mobile transformer? Something on a skid or a truck?

The GEC is nice to have, but the SBJ is a must to have

On skid

So no GEC is ok if you don’t have it around. If the SBJ bonded to XO is enough

I've been curious about this too. Often see portable transformers on carts at convention centers, never a GEC.

Mines are not in the scope of the NEC. The are under OSHA and MSHA. So my answer does not apply

Tom sorry I will take it back, when you meant “mine” I misread it wrong, this portable transformer is for marine environment

Hmm it makes sense other wise why portable but That means it’s not NEC code compliance
