Do I need shunted or non shunted?

If your existing light fixture shows positive continuity when testing both contacts on a single socket (usually the meter will beep), there is power flowing between the two contacts, and this is a shunted tombstone. If there is no power between contacts, it is a non-shunted tombstone.

Can you convert shunted to non shunted?

7 Answers. You can’t hack a shunted lampholder to be a non-shunted unless it’s designed to do that. For one thing there is no place to attach the wires. Yes, there are two wire holes, but a non-shunted holder has four.

What is the difference between shunted and non shunted lamp holders?

Are T8 tombstones shunted?

Non-Shunted Rapid Start Tombstones like this are needed. T8 fixtures must have the input side sockets changed to T12 sockets of the “Non-Shunted Rapid Start” type, as T8 sockets have a circular conductor that will not allow them to properly separate the line and the neutral sides of the circuit.

What is the difference between shunted and Unshunted tombstones?

Shunted tombstones have two joined electrical contacts internally which allows you to create a single track for the electrical current. An unshunted tombstone has separate points of entry, or contacts, for the wires which will create two tracks for the electrical current.

What is shunted and non shunted lampholder?

On a shunted socket, the contacts are connected internally, which means continuity is present for both of the contacts. With a non-shunted socket, there is no continuity present between the contacts since the contacts are not connected internally and require separate power leads.
