I haven't seen an explicit rule regarding the elemental effects. However, there are explicit rules regarding contact style effects, such as toxins and fire elemental effects. For toxin effects, complete protection (chem suit and armor with sealing) is provided even with an injector style attack. If completely soaked, the injection toxin has no effect because it never breached the defense of the target.
Similar effects come from the fire resistance armor addon. Fire effects have a chance to ignite the target, unless the target is incombustible. This can be achieved with appropriate gear (fire resistant or retardant gear). If a fire attack is resisted, then the target does not ignite.
Both of these attacks are contact style attacks (fire doesn't have any "force" to it, per se, it just needs to get on you). Complete or near complete isolation provides protection. While there is no explicit rule stating this, electrical attacks that fail to breach the protection of a suit outfitted with resistance should be ignored for the disorientation effects.
However, this means that the armor has to resist all the electrical damage. If even a single point gets through, I would say there may be a chance of the disorientation effect. Of course, individual GM's may not be that nit-picky, and simply count the fact that electrical resistance was there as the opportunity to resist the effect. Note that this isn't spelled out in the book, but is an interpretation of the rules. As such, expect arguments regarding this.
