Let me get this straight.
You get a suit that may prevent an Arc blast harming you and all of a sudden it's OK to work live?.
If your boss or foreman requires that you work hot when they aren't there to assess the situation,get them to come to the site and do it themselves.
And, do they require you to work by yourself?.
Get this, under company policy here, it is a dismissable offence to require any worker to work with live conductors or isolators where it is not possible to de-energise such equipment or lines.
Every person that is working on a live installation or works shall have 2 helpers (being suitably qualified) and a Safety Observer.
PPE or no PPE, just be very aware that your actions (or in-actions) can have serious results.
