Heater Connectors

[bluerose]

Hi To All
in my company we have an ACP line which contains many heaters.
our problem is that our electrical connector damage very soon.
(3 phase heater - 20 amps per phase - 400 c) .we use copper leads .
is it possible guide me to choose suitable connectors .
my friend suggest to use Nickle Connector. is that true?
best regard.

Heater connections must be done with nickel terminals, crimped with the appropriate tool. For a conductor, I'd recommend TGGT. Both the conductor and the terminal at the heater connection must be rated for the heater's temperature for assured long life and good service.

we typically use uninsulated crimp on terminals. but for most of our heater applications the connection point is open and does not get real warm.

use a method suitable for the temperature the wire and connection will see.

The heater manufacturer should have the recommended(requyired) connection method and materials specified, or temperature data given at the connection points so that the proper connector can be selected. UL would require this information to be part of the installation instructions.

Of course if you are using a non-listed heater, you may be on your own......

Unfortunately we are using an ACP line that manufactued in CHINA
without any documentation or technical paper.
