FREQUENTLY ASKED QUESTIONS

"Does SEBCO sell their low-voltage transformers to anyone?"

No, SEBCO only sells low-voltage transformers to OEM's, Electrical Warehouses, and Distributors.  If an electrician or                     contractor would like to purchase one our low-voltage transformers, they can simply call us and we will direct them to the nearest OEM, Electrical Warehouse, or Distributor that sells our products.

"Does SEBCO offer an open account for OEM's and Electrical Wholesalers?"

Yes, SEBCO offers 30 days terms to all qualified buyers.  All of the major Wholesale Electrical Distributors are already "Set-Up!"  All we need is a purchase order to release goods.

"Why does my low-voltage transformer keep tripping?"

 Low-voltage transformers trip for a number of different reasons.  For example, if the load you are hooking up exceeds the amount of the wattage on the nameplate of the transformer, the circuit breaker in your transformer will trip, protecting both the transformer and your lights!   To estimate the load, multiply the watts per bulb by the total amount of lights in your run.

For example: If you have 5 lights that are 50 watts each, { 50 x 5=250 } your total "rated" wattage is 250 watts.  If these are Halogen lights, then you should add 5% as a safety factor.  This would make your total Lighting load 263 watts. Next, you must take into consideration the length of the run and the size wire you are using.  14 gauge wire is often supplied with low voltage lighting "kits" , but it is generally used with very low wattage bulbs: 5,7,or 10 watts.  12  gauge wire is only rated for 20 amps ( 12 volts x 20 amps = 240 watts ) so the above load is already larger than the wire can handle.  Using wire too small increases the resistance and "adds" to the load.  This means your lights will not work properly.  SEBCO would recommend 10 gauge wire "minimum" and a 300 watt transformer. If the run is long, it might be wise to use 8 gauge wire to insure proper voltage at the fixture.


"What is a multi-tap transformer?"

A "multi-tap" transformer is one that has several voltages on the secondary side.  Usually, 12, 13 and 14 volts.  Some go higher, but may or may not be properly listed for outdoor lighting.  The U.L. Standard for low voltage, outdoor lighting systems is U.L. 1838.  This standard states that systems may only go up to 15 volts.
