I know of no reason you cannot use other than brown / blue inside your product. I have had occasion to use both intermixed in a product. The TUV guys preferred that brown/blue was the mains wiring up to the primary of the transformer. The secondary side was mixed with black/white. Never saw a requirement in writing but eventually got tired of explaining so we now use brown/blue exclusively for anything mains related. In fact, we prohibit brown/blue for use on any other voltage than mains. And as always, green / yellow is the only earth ground color; again, its use is exclusive. We have no problem from CSA with this scheme. Regards, Scott [email protected]
