T1 Surge Protective Device (SPD) are intended for installation between the secondary of the service transformer and the line side of the service equipment overcurrent device, as well as the load side, including watt-hour meter socket enclosures, and are intended to be installed without an external overcurrent protective device.

T1 devices are dual-rated for T2 applications as well, providing the highest ratings available for installation at the service entrance. T1 SPD can discharge lightning current with waveform 10/350 μs. It will be installed in the primary distribution board at the origin of the electrical installation. T1 SPD does not in itself offer the required protection level and must be used in conjunction with coordinated T2 devices.

An installation with a lightning protection system will require a T1 SPD. T2 Surge Protective Device are intended for installation on the load side of the service equipment overcurrent device, including SPDs located at the branch panel. T2 SPD can discharge 8/20 μs current wave, they can prevent the damage of transient overvoltage in the electrical installations and can protect equipment connected to it. It usually employs metal oxide varistor (MOV) technology. The device would normally be installed in sub-distribution boards and in the primary distribution board if there was no requirement for a T1 device.
