nVent CADDY T313 – Frequently Asked Questions

1) What is the nVent CADDY T313 card cloth brush actually used for?
The nVent CADDY ERC T313 is a card cloth brush used to prep surfaces before an exothermic weld. Installers use it to clean conductor and cable ends, and the connection surface, so the weld takes cleanly. It is a preparation tool, not a weld component itself, and it gets used alongside the welding material and mold.
2) Does the T313 brush come with the weld mold and welding material, or do I order those separately?
The T313 is sold as the brush alone. It is an accessory meant to be used with exothermic welding materials, molds, and the related consumables, so the mold sized for your conductor and connection type, plus the weld metal, are separate line items on the order.
3) Is a card cloth brush necessary before making an exothermic ground weld, or can I skip it?
Surface prep is part of the exothermic welding process, and the ERC T313 exists to do that step. Oxide, dirt, or moisture left on the conductor or the surface being welded is what causes a porous or failed connection. Brushing the cable end and the mating surface first is what makes the result repeatable from splice to splice on a grounding grid.
4) What part number do I give my supplier for the nVent CADDY card cloth brush?
Order it as nVent CADDY T313, from the ERC exothermic welding line. There is a single model, so there are no size, length, or finish choices to specify.
5) Is this brush suitable for grounding and bonding work on a conduit and raceway system?
That is the work it is built for. The ERC T313 is used on electrical conduit and raceway installations where exothermic weld connections carry grounding and bonding, including ground grid and bonding jumper terminations made in the field.
6) Is the T313 a one-time-use consumable or a reusable jobsite tool?
The T313 is a reusable hand tool, not a consumable that is spent in the weld. The weld metal and the mold are what wear out over repeated shots; the card cloth brush stays in the kit and gets used before each weld. Crews doing high shot counts typically keep a spare in the truck since the card cloth surface does eventually dull.
