Determining the acceptability of an SPD for UL 508A Control Panels and All Other UL Listed Equipment
The UL inspector will first consider the SPD type when determining it’s acceptability for a given application or piece of equipment. This will include UL 508A as well as all other UL Listed equipment. The first level compliance is based on the UL Approval (LISTED or RECOGNIZED) of the SPD or UL SPD Type and it’s Suitable Ratings. This means that it has to meet all safety, performance, environmental and electrical system ratings of the application. If any of these criteria are not fully met, it will require a Procedure Description, a File Update and/or Additional Testing. These actions will require additional costs that may be substantial. For this reason, it is in the interest of the specifier to use UL LISTED SPD’s to eliminate any uncertainty or to make sure the UL RECOGNIZED SPD is selected at the time of UL submittal of the equipment.
Approval Considerations Table based on UL SPD Type
UL Mark | UL 1449 SPD Type | Suitable Ratings | Procedure Described | File Update or Additional Testing | Notes |
|---|---|---|---|---|---|
| 1 2 | Yes | No | No | The only requirement is that the SPD must match electrical and environmental ratings of the UL 508A Control Panel. A UL field inspection of the control panel with the SPD installed is required as a part of a standard follow-up service visit. |
| 1CA 2CA 4CA 5 | Yes | Yes | Yes | Yes – All UL recognized SPD’s require a UL engineering evaluation of the SPD’s existing UL 1449 E–file. This will result, at a minimum, in a cost to update the UL file and may also require testing that would result in additional costs. |
