I understand that Dielectric Strength relates to the point where a compound breaks down under electrical load. Please correct me if I have it wrong. I want to now if an RTV compound (with Dielectric Strength of approx 500 volts/mm) is safe to use across 240v or 415v terminals that are 3-5mm apart. Do i understand it that if one applies 500v and the RTV gap is 1mm that it would break down and conduct. Lower voltage or larger gap and it would not conduct and therefore be safe? Very much appreciate any feedback.
