Product Details
When purchasing a terminal strip to replace one that's melted, the following should be taken into consideration:

1.  The wiring at the terminal strips is usually carrying high voltage, high current power from from the the main power line that powers your sauna as well as the power lines leading to your heaters, and can be lethal.  Always unplug your sauna before attempting any repairs or replacing parts in this area!  

2.  The most common reason terminal strips fail is because of overheating that occurs due to connections that are not tight enough, oxidized, corroded, or otherwise unable to make a solid connection.  These are factors that introduce resistance in the circuit.  This resistance causes a "traffic jam" of electrical current to be given off as heat at that location.  Once compromised, over time this continued repetitive build up of heat will typically warp, distort, or melt the plastics of the terminal strip and/or protective lens.  It's therefore recommended that a terminal strip be replaced the moment that it shows any signs of melting or overheating.

3.  While not available in all current values, gold plated connectors are especially advantageous in environments that are highly prone to metallic oxidation and corrosion, such as being near an ocean or a humid climate.  Gold is actually less conductive than copper or silver, but gold does not corrode or oxidize.  Therefore we recommend those who's saunas are located near a coastline or otherwise in a humid environment consider the gold plated terminal strips.

4.  When replacing a terminal strip that was compromised due to overheating or melting of the surrounding plastic, it's strongly recommended that the current rating of the replacement exceed the original, and make sure that the ends of the connecting wires are all tightly crimped, and all screw terminals are screwed down tightly.  While they do cost more, our heavy-duty 3 and 4 position terminal strips are designed to carry as much as twice the current that most saunas are designed with.  While this might sound like overkill, these heavy-duty terminal strips also incorporate better plastics capable of withstanding higher temperatures in the event that poor connectivity should occur due to oxidation, loose connections, or any other potential issues.  Furthermore, it's important to consider that general purpose terminal strips used in many consumer infrared saunas are rated for ideal conditions that sometimes don't always factor in thermal extremes, outdoor use, etc.  For this reason, consider a heavy-duty terminal strip for the greatest thermal tolerance and sustained electrical continuity over years of use.

5.  When reconnecting the wiring, please consider the following:
  • Solid copper wiring should in most cases probably be fine, but crimped connectors should be replaced, especially those showing oxidation and any tarnishing of the copper wire at or near the failed connection should be cleaned before replacing the connector.
  • Stranded copper wiring at or near a failed connection may be compromised.  The easiest way to check for this is by checking to see if the wiring is still malleable near the connection.  It should be easily bendable.  Any part of the wire that is at all stiff should be cut away.  If there isn't enough slack, then that line should simply be replaced.  In many cases when replacing wiring, we will typically go to the next lower gauge wiring than the sauna was originally built with, as this is usually only a marginal increase in cost, but can only further improve the current throughput and provide a wider pathway for electricity to flow.  Like solid copper wiring, all connectors near the failed connection should be examined for oxidation and cleaned or replaced and tightly crimped.
And as always, feel free to contact us if you have any questions.
